BMW’s are known to have failure prone front thrust arm bushings. The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change. This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience. Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure.

Rubber mounts in any position of a vehicle are usually designed with comfort and longevity in mind leaving performance as a sacrifice. This kind of sacrifice here at Turner just won't do, so we did what we do best and designed a solid monoball mount.

Our engineering team first wanted to tackle the issue with wear found on rubber mounts. Due to their combination of steel, rubber, and low mounting location, these mounts are a direct target for deterioration and failure. As they are positioned out in the open and exposed to the elements, bonded steel and rubber components inevitably hold moisture, separating as the steel bearing begins to rust. Our solution was to offer a rebuildable mount with a Teflon lined bearing for increased durability, combined with a blue anodized body and melonite coated bushing sleeves for corrosion resistance.

The performance side of these mounts is primarily found in the articulation allowed by the bearing. Rubber mounts do not allow for proper free damper movement, hindering shock performance. By eliminating the deflection found in factory rubber mounts and allowing full shock articulation, this solid monoball design eliminates slop and maximizes shock efficiency and performance, allowing for more predictable handling on the street or the track - with almost zero added noise, vibration, and harshness.

 

Replaces OE part #: 33526768544

 

Key Benefits:

  • Monoball rear lower shock mount eliminates unwanted deflection, maximizing shock efficiency and performance.
  • Allows full shock body articulation for low friction movement and reduced side loading and improved shock wear.
  • Designed to work with stock non-M taper seat stud style shocks (not M eyelet mount type).
  • Maintains OE shock position

 

Design features:

  • Rebuildable using off the shelf bearings - these are the last rear shock mounts you’ll need to buy
  • Includes new hardware
  • Made in USA

 

Housing:

  • Billet CNC 6061-T6 aluminum housing, type II anodized for exceptional durability and corrosion resistance

 

Bearing:

  • FK WSSX14T teflon lined spherical bearing
  • 440C heat-treated stainless steel ball, 1 ⅜” ball dia.
  • 17-4 PH heat-treated stainless steel race
  • Self-lubricating PTFE liners are chemically bonded to the inner diameter of the race to offer a very high load-carrying capacity with greatly increased dynamic wear characteristics.
  • Static Axial Load Rating: 10,800 lbs.
  • Rod End Misalign Angle: 6 degrees

 

Bearing inserts:

  • CNC machined 1144 steel, heat treated and melonite coated designed to maximize ball articulation while offering exceptional durability and corrosion resistance.

 

This item fits the following BMWs: 
2008-2013 E82 BMW 128i 135i 135is Coupe 
2006-2011 E90 BMW 325i 325xi 328i 328xi 328i xDrive 330i 330xi 335d 335i 335xi 335i xDrive - Sedan

Our sealed Monoball Rear Trailing Arm Bushings (RTAB) are the best solution for completely eliminating deflection and unwanted toe changes on the rear of the E36, E46, and Z4. While rubber and urethane bushings flex during load, the toe can change widely giving you nervous and unpredictable handling. These RTABs have a solid aluminum housing with a high-quality sealed OE bearing. These bushings were developed from years of competition use in various racing and HPDE events. There is simply no better RTAB unless your racing class rules prohibit the use of mono or spherical bearings.

The rear trailing arm bushings take a lot of abuse from acclerating, braking and cornering. The stock rubber bushings are just not up to the task of keeping rear wheel alignment in spec for very long, especially if you have upgraded to stickier tires and a better suspension. The pliable rubber flexes and twists which slows down reaction time and leaves you with a car that feels nervous and 'tail happy'. Urethane helps to control the alignment but issues with fitment, maintenance, and longevity keep us from recommending urethane on anything but a street car. We also offer a Delrin RTAB for cars that must conform to certain racing class rules. These sealed spherical bearings are the best at controlling rear toe alignment.

Our aluminum RTABs are very well made - high grade aluminum alloy and steel CNC'd out of a billet by an ISO 9001 certified manufacturer, each component is either hardcoated or nickel plated. While multiple manufacturers offer two piece designs, our research showed that a one piece bushing is a better design featuring a sealed bearing to keep contaminants out extending the life of the bearing.

Features:

Key Benefits:

  • Rear Trailing Arm Monoball eliminates unwanted deflection, maintaining alignment settings and minimizing wheel hop.
  • Allows full rear trailing arm articulation for low friction movement and eliminates binding found in rubber and poly bushings.
  • Completely streetable: utilizes an OES Lemforder brand sealed, greased ball joint for an extremely long service life with no increase to NVH.

 

Design Features:

  • Housing: Billet CNC 6061-T6 aluminum, type II anodized for exceptional durability and corrosion resistance
  • Bearing: OE Mercedes/lemforder 2043520027 Sealed ball joint
  • Bearing inserts: CNC machined 303 stainless steel.
  • Rebuildable

BMW’s are known to have failure prone front thrust arm bushings.  The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change.  This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience.  Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure. 

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!  Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).  We wanted to offer E31, E32, E34, E38, E39, E53, E60, E63, E64, and E83 owners similar levels of handling precision and control for the track and street. 

The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise.  We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting.  The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment.  What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.

We offer these thrust arms with the monoball bushings pre-installed for your convenience. Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms.

Features:

Bearing housing

  • Precision CNC machined from 6061-T6 blue anodized aluminum
  • Knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands.
  • CNC machined 304ss ball joint sleeve inserts, providing a precision fit between the ball joint and the subframe. 

Bearing

  • OEM BMW sealed and greased ball joint for exceptional durability and service life.

Performance

  • Nearly instantaneous, crisp steering and braking response.
  • Maintenance free, long lasting performance. 
  • Improved road feel without undesirable NVH.

Stock rubber front control arm bushings are designed to allow significant fore/aft movement of the front wheels to help absorb road impacts.  This soft flexible design maximizes daily driving comfort and helps to add the “luxury” feeling to your BMW, but it is far from ideal for the performance or racing enthusiast that is looking for optimal handling and braking performance.  Being a bonded rubber bushing that is constantly twisting and deflecting when in use, stock rubber bushings really take a beating and often fail prematurely, resulting in further degraded handling, braking shimmy or even clunking felt under your feet.

In the past, the only upgrade option to improve handling of your E46 M3 was to replace the stock rubber with poly bushings, or delrin bushings that wear prematurely and are not serviceable or rebuild-able.  While well-designed poly bushings can vastly improve handling characteristics and offer good road feel with minimal increase to NVH, they are still a compromise when it comes to ultimate handling and braking performance.

Introducing the new Turner Front Control Arm Spherical Bearings!  The Turner engineering team set out to design a no-compromise solution that requires no modification and offers instantaneous cornering and braking response.  Our control arm bearings utilize a unique grease-able spherical bearing that is both serviceable and replaceable, with integrated dust seals to help keep dirt and moisture out.  This bearing offers considerable improvement in both precision and durability compared to other unsealed poly and delrin bushing inserts previously available, which can wear prematurely due to contamination.  The bearing assembly utilizes the highest quality materials, precision machining quality, and components to ensure a perfect fit and longest lasting component life possible.

The result is the ultimate in terms of low friction, no binding, and no unwanted deflection, as well as exceptional steering precision, turn-in response, and direct braking feedback with minimal increase in NVH.  These spherical bearings are a must have for any track car, but are also completely street-able and are a great upgrade for any enthusiast that enjoys spirited driving.

Features:

Bearing

  • Extremely robust, greaseable, double lip sealed spherical bearing (Rated for 20,000lbf Dynamic, 90,000lbf Static). 

Housing

  • 6061-T6, anodized housing with needle grease zerk for easy maintenance. 
  • In house designed knurled OD to provide the perfect fit for the wide range of housing diameters among brands. 

Bearing Insert Arm adapter

  • Precision CNC machined Delrin, providing a tight fit between the bearing and the control arm. 

Performance

  • Instant, crisp steering and braking response.
  • Easy to maintain, long lasting performance. 
  • Improved road feel without undesirable NVH.

Grease before installation and with each oil service with high quality Moly grease for maximum service life.  Need a Grease tool?

Made in the USA TMS rear subframe bearings are designed to limit rear control arm movement relative to the subframe. The stock BMW subframe bushings are made out of rubber, which allows variance in suspension position due to deformation and compression. A race car needs to have all suspension points remain in place for proper setup. By using high grade aircraft aluminum alloy and high performance race bearings, the TMS bushing replacements are both lightweight and strong. The casing is designed so that if maximum motion occurs, the load will be evenly distributed throughout the casing. Our flanges are designed to spread the load on the subframe and limit movement. The bearing we use is an extra wide race bearing to distribute the load over a broader area. Each piece is anodized or nickel plated to withstand corrosion. These bushings are a perfect compliment to the TMS lower camber arms.

Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).  We wanted to offer e30, e36, and e46 owners similar levels of handling precision and control for the track and street, but weren’t satisfied with the other options out there.  Instead of a Delrin® bushing or unsealed spherical bearing alone, we selected an oversized sealed greaseable spherical monoball to offer unparalleled durability and precision, but designed a Delrin® adapter sleeve to help isolate the added noise, vibration, and harshness that a full solid monoball bearing will have. While race-ready, our hybrid Delrin®/monoball control arm bearings are more at home on the street than other kits that are advertised as “race-only” bearings. We did extensive street, autocross, and track testing to ensure the spherical bearing used in this bushing design excelled in each setting.

The stock rubber bushings, even those found in the M3, allow significant fore/aft movement of the front wheels to help absorb road impacts, especially when being pushed hard.  This soft flexible design maximizes daily driving comfort, but also allows considerable alignment change.  This unwanted deflection stands between you and a crisp, confidence-inspiring driving experience.  The advantage of a monoball bearing is that it will not deflect under load, eliminating all unwanted deflection while still allowing complete freedom of movement in the desired angles. What you get is superior steering precision with better handling from more consistent alignment and direct braking feedback, with exceptional service life.  Thanks to the Delrin® insert and double lip seals, there's none of the extra noise or reduced service life often found on other spherical bearings.

In short, if you're seeking front control arm bushings that offer precise, predictable handling, crisper braking feel, with a long service life free from noise - look no further. We have you covered.

It’s no secret that BMW’s suffer from weak, failure prone front thrust arm bushings.  The stock rubber bushings are designed to allow significant fore/aft movement of the front wheels and are fluid filled to help absorb road impacts.  This compliant design maximizes daily driving comfort and helps add to the “luxury” feeling of your BMW, but it also contributes to the numb, disconnected feeling that many enthusiasts complain about with modern BMW’s.  Not only is the OEM design far from ideal for the street or racing enthusiast that is looking for optimal handling and braking performance, the constant twisting and deflection required of the rubber bushing often causes premature failure, resulting in degraded handling, wheel shimmy, delayed steering response, delayed braking response, unwanted alignment change, and poor tire wear.

Introducing the new Turner Thrust Arm Ball Joints!  The Turner engineering team set out to design a solution that offers far superior durability when compared to OEM, requiring no modification and offering nearly instantaneous cornering and braking response for the absolute best road feel and driving experience possible.  Our thrust arm monoballs utilize a sealed OEM BMW ball joint for exceptional quality and durability.  The bearing assembly is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit and longest lasting component life possible. 

By utilizing a sealed ball joint, Turner achieved the ultimate in terms of low friction no bind suspension travel with no unwanted deflection, providing exceptional steering precision, turn-in response, and direct braking feedback; all while maintaining exceptional comfort and durability levels making these an excellent no compromise upgrade even for a street car.  These thrust arm monoball / ball joints are a must have for any track car, but are also completely street-able and are a great upgrade for any enthusiast that enjoys spirited driving.

BMW’s are known to have failure prone front thrust arm bushings.  The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change.  This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience.  Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure. 

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!  Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).  We wanted to offer E31, E32, E34, E38, E39, E53, E60, E63, E64, and E83 owners similar levels of handling precision and control for the track and street. 

The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise.  We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting.  The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment.  What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.


We offer these thrust arms with the monoball bushings pre-installed for your convenience. Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms.

Features:

Bearing housing

  • Precision CNC machined from 6061-T6 blue anodized aluminum
  • Knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands.
  • CNC machined 304ss ball joint sleeve inserts, providing a precision fit between the ball joint and the subframe. 

Bearing

  • OEM BMW sealed and greased ball joint for exceptional durability and service life.

Performance

  • Nearly instantaneous, crisp steering and braking response.
  • Maintenance free, long lasting performance. 
  • Improved road feel without undesirable NVH.

This item is an upgrade to the following rear-wheel drive BMWs:

Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).  We wanted to offer e30, e36, and e46 owners similar levels of handling precision and control for the track and street, but weren’t satisfied with the other options out there. Instead of a Delrin® bushing or unsealed spherical bearing alone, we selected an oversized sealed greaseable spherical monoball to offer unparalleled durability and precision, but designed a Delrin® adapter sleeve to help isolate the added noise, vibration, and harshness that a full solid monoball bearing will have. While race-ready, our hybrid Delrin®/monoball control arm bearings are more at home on the street than other kits that are advertised as “race-only” bearings. We did extensive street, autocross, and track testing to ensure the spherical bearing used in this bushing design excelled in each setting.

The stock rubber bushings, even those found in the M3, allow significant fore/aft movement of the front wheels to help absorb road impacts, especially when being pushed hard.  This soft flexible design maximizes daily driving comfort, but also allows considerable alignment change.  This unwanted deflection stands between you and a crisp, confidence-inspiring driving experience.  The advantage of a monoball bearing is that it will not deflect under load, eliminating all unwanted deflection while still allowing complete freedom of movement in the desired angles. What you get is superior steering precision with better handling from more consistent alignment and direct braking feedback, with exceptional service life.  Thanks to the Delrin® insert and double lip seals, there's none of the extra noise or reduced service life often found on other spherical bearings.

In short, if you're seeking front control arm bushings that offer precise, predictable handling, crisper braking feel, with a long service life free from noise - look no further. We have you covered.

BMW's are notorious for their failure-prone control arm bushings. The pliable rubber bushings, present even in M performance models, allow substantial movement of the front wheels to enhance everyday driving comfort. However, they also permit significant alignment changes, leading to a disconnected and numb road feel that detracts from a confidence-inspiring driving encounter. Over time, the fluid-filled rubber bushings succumb to fatigue and cracking due to continual deflection and ozone degradation, ultimately resulting in the leakage of damping fluid and complete failure.

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!

BMW’s are known to have failure prone front thrust arm bushings.  The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change.  This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience.  Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure. 

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!  Our experience with spherical front control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).  We wanted to offer E31, E32, E34, E38, E39, E53, E60, E63, E64, and E83 owners similar levels of handling precision and control for the track and street. 

The bearing housing is precision CNC machined from 6061-T6 anodized aluminum and features a knurled OD to ensure a perfect press fit, and utilize a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise.  We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting.  The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment.  What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.


We offer these thrust arms with the monoball bushings pre-installed for your convenience. Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms.

 

Features:

Bearing housing

  • Precision CNC machined from 6061-T6 blue anodized aluminum
  • Knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands.
  • CNC machined 304ss ball joint sleeve inserts, providing a precision fit between the ball joint and the subframe. 

Bearing

  • OEM BMW sealed and greased ball joint for exceptional durability and service life.

Performance

  • Nearly instantaneous, crisp steering and braking response.
  • Maintenance free, long lasting performance. 
  • Improved road feel without undesirable NVH.

BMW's are notorious for their failure-prone control arm bushings. The pliable rubber bushings, present even in M performance models, allow substantial movement of the front wheels to enhance everyday driving comfort. However, they also permit significant alignment changes, leading to a disconnected and numb road feel that detracts from a confidence-inspiring driving encounter. Over time, the fluid-filled rubber bushings succumb to fatigue and cracking due to continual deflection and ozone degradation, ultimately resulting in the leakage of damping fluid and complete failure.

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available! Our experience with spherical control arm ball joints go back to those we designed and used in our IMSA E90 328i and E92 M3 racecars (GS class Champions in 2011).

M3 upper and lower control arms are a known upgrade for non-M E82 and E9X chassis. But our Monoball Thurst Arms are even more of an upgrade over the stock M3 arms. This package bundles the Turner Monoball upper thrust arms with the stock M3 lower control arms. If there's one big fail point in the E82/E9X front suspension it's the thrust arms. The front inner thrust arm bushing is filled with dampening fluid that leaks over time. Once it's gone the bushing has the strength of a rubber band. Even though we sell two types of upgraded rubber bushings there was still room for improvement. For someone looking for superior performance and longevity these sealed monoball bushings are the best out there. 

The advantage of a monoball bearing is that it will not deflect under load. All of the rubber bushings, including the M3, move in all sorts of directions and that changes your alignment, especially when used with big brake kits or when driven hard. And when worn out, performance suffers. Our monoball sits in a CNC machined aluminum housing which has zero deflection. The monoball allows complete freedom of movement but only at the desired angles. What you get is superior steering precision, better handling from more consistent alignment, and almost infinite bushing life. And thanks to the inner liner and sealed rubber boots there's none of the extra noise or reduced service life of fully solid race bushings.

The lower M3 control arm bushings use a similar sealed monoball bushing instead of rubber. This package gives you monoball precision and performance with OE-quality components.

This item fits the following BMWs: 
2008-2012 E82 BMW 128i 135i 1M Coupe

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!  Our experience with spherical front control arm ball joints goes back to those we designed and used in our IMSA E90 328i and E92 M3 race cars (GS class Champions in 2011). We wanted to offer as many BMW owners possible a similar level of handling, precision, and control for the track and street.

Utilizing a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise.  We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting. The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment.  What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.

 

 

 

 

 

 

 

We also offer these control arms with the monoball bearings pre-installed for your convenience. Since BMW recommends the control arms be replaced for every other bushing change, we prefer to sell these as a pre-assembled set. The bushings are also available separately if you wish to source your own control arms.

 

Control Arm Bearing

  • CNC machined corrosion resistant 304 Stainless steel shell, bolt sleeves, & snap rings
  • Sealed spherical ball joint for long service life & maintained OE fitment
  • Suspension pre-load is no longer required when torquing the control arm hardware

 

Thrust Arm Bearing:

  • OEM BMW sealed, greased ball joint for exceptional durability and service life, even in the most severe operating conditions
  • 6061-T6 anodized housing for excellent corrosion resistance
  • Proprietary Turner designed knurled OD to provide the perfect fit for the wide range of thrust arm bore diameters among brands
  • CNC machined 304ss, providing a precision fit between the ball joint and the subframe

 

Benefits of Both:

  • Nearly instantaneous, crisp steering and braking response.
  • Maintenance free, long lasting performance.
  • Improved road feel without undesirable NVH.

Includes Turner Motorsport Monoball front control arm bushings! Our engineers designed this race kit which allows +10mm more track width (per side) than stock. Wider track width reduces the amount of load transfer to the outside when cornering, increases cornering power, and allows more inner clearance for meaty wheel and tire setups or brake ducts.

BMW’s are known to have failure prone front thrust arm bushings.  The flexible rubber bushings, even those found in M performance models, allow significant movement of the front wheels to maximize daily driving comfort, but also allow considerable alignment change.  This results in a disconnected and numb road feel, standing between you and a confidence inspiring driving experience. Eventually the fluid filled rubber bushings fatigue and crack due to continual deflection and ozone degradation, and eventually the damping fluid leaks out resulting in complete failure.

For the enthusiast looking for superior performance and longevity with a crisp, confidence-inspiring driving experience, our sealed ball joint monoballs are the best solution available!  Our experience with spherical front control arm ball joints goes back to those we designed and used in our IMSA E90 328i and E92 M3 race cars (GS class Champions in 2011). We wanted to offer as many BMW owners possible a similar level of handling, precision, and control for the track and street.

Utilizing a sealed OEM BMW ball joint for exceptional quality and durability, making them completely at home on both the street and track with no compromise.  We have done extensive street, autocross, and track testing to ensure the ball joint used in this bushing design excels in each setting. The advantage of a sealed ball joint is that it eliminates all unwanted deflection while still allowing complete bind-free movement throughout suspension travel, resulting in exceptional control of wheel alignment.  What you get is superior steering precision, turn-in response, direct braking feedback, and better handling.

In short, if you're seeking the ultimate in precise, predictable handling and control, with crisp braking response and a long service life that’s equally at home on the street or track - look no further. We have you covered.
