These adjustable rear links are only required when using sway bar / swaybars with a suspension with a very low ride height, where it may be necessary to adjust the length of the end links for proper sway bar clearance from the drive axles or other suspension components. These suspensions are usually found only on race cars but this may also apply to street cars with sport springs/sport coil overs that are lowered a lot. On most street cars lowered 1.5" or less, the stock links will be fine.

These end links feature a Heim joint, which allows enough lateral movement when disconnected to adjust the length of the link without removing the entire link from the car. This is particularly helpful when eliminating or adjusting preload while tuning the suspension. Similar links without this joint, can't be adjusted without totally removing the link from the car.

Built-in grease fittings allow for occasional lube, and a packet of grease is included. These links are sold as a set, and include two end links and hardware for H&R and TMS sway bars (other brands may not need the hardware). 

At their shortest setting they are 2.875" hole to hole and on their longest setting they are 3.5" hole to hole.

*Note: these links will not work with factory or non-adjustable Eibach sway bars.

Stock rear lower control arms offer very little adjustment for alignment, especially in lowered vehicles, due to their use of an eccentric bolt. These aftermarket performance control arms from ECS Tuning are designed for maximum adjustability, allowing you to maximize handling and minimize tire wear.

To ensure maximum reliability, ECS Tuning's control arms are constructed from strong, lightweight 6061-T6 aluminum and feature a 303 stainless steel center turnbuckle that offers over 8 degrees of fast and precise camber adjustment. The inner bushing is a stock style serviceable OEM bushing for long life and inexpensive maintenance.

Features:

Durable construction suitable for the daily driver and track car alike
8+ degrees adjustment range for dialing in any suspension and wheel/tire setup
Center located adjuster for maximum clearance during adjustment
OEM-style bushing for long life and inexpensive service
Black anodized 6061-T6 aluminum with 303 stainless steel turnbuckle
Includes new hardware
*With the exception of the stance community, most enthusiasts will need no more than a few degrees of adjustment range. Total adjustment often is dependent on wheel/tire clearances.

A very common weak point on the 3 series BMW is the sheetmetal of the rear shock tower. The sheetmetal here is relatively thin and very susceptible to stress and fatigue. A worn out shock will bottom-out more often and this energy is transferred through the bump stop and into the metal chassis. Stiffer shocks and shock mounts also put more stress on the sheetmetal. Factor in age, mileage, and environmental conditions and it's not a surprise that we see shock tower failures often. BMW addressed this issue with reinforcements of their own but our's are thicker for additional strength. This kit mounts on top of the shock tower and can either be bolted or welded in place. Because of the shape of the rear shock tower, these do not fit cabrio/convertible cars.

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.

Worn rubber differential mounts will lead to the differential twisting and shifting around in the rear subframe. Not only will this be noisy but it's bad for driver confidence and bad for the chassis as well. Even on fresh rubber bushings the differential has deflection and twist, especially if the car has been modified for more torque. Since the differential is centrally mounted in the rear subframe, with all suspension mounts interconnected, a differential with too much deflection will affect handling and could even damage the rear subframe.

These 88A urethane E46 M3 diff mounts are much stiffer than stock but still not as solid as our Turner aluminum/Delrin bushings. This set will resist twisting much better than the stock rubber mounts. Included is the front diff mount and two rear mounts in the cover.

Made in the USA The rear subframe is the heart of the BMW rear suspension. Not only do all of the suspension arms attach to it, the driveline runs through it via the differential and half-shafts. Therefore, a track-prepped E46 should never see any flex or deflection in any of the subframe mounts. Excessive movement here transfers to unwanted suspension motions elsewhere and is also a major contributor to failures in the rear floor sheetmetal.

While our Delrin-Aluminum subframe mounts conform to various racing series these all-aluminum mounts are the ultimate in reducing flex and deflection. The rubber stock mounts, and the Delrin mounts to a small degree, flex and deflect as various forces are applied throughout the subframe - on and off throttle loading, cornering on flat surfaces, bumpy surfaces, weight transfer, sticky race tires, etc. Too much flex from worn rubber mounts will transfer to flex where the subframe meets the chassis/floor. This is the primary cause for the infamous rear subframe failure. These fully solid aluminum mounts have absolutely zero flex to them so they will not contribute to rear subframe issues. The Turner E46 Reinforcement Kit is still recommended.

These solid subframe mounts were designed for racing use only, where we won several sports car championships in the Grand-Am Cup series. These subframe mounts are over-engineered to be a major improvement over the stock subframe mounts not only for performance but also in strength as well. The aluminum is CNC machined for a precise fit and minimal weight. One front bushing is slotted to allow for BMW's manufacturing tolerances. Professional and experienced installation is required.

The E36/E46 rear trailing arm bushings (RTABs) wear out faster than any other bushing on the car. Worn RTAB will cause excessive toe alignment change and give a 'loose' or 'floaty' feeling in the rear handling. One of the reasons for this is that they over-extend during motion, stretching and twisting the rubber in all directions. These shims sit on either side of the bushing and limit the amount of extension from the bushing. Not only will you get more life from your RTAB but these will help stiffen the bushing during cornering. But during normal driving you will still have all of the comfort of the stock rubber bushings. These part about these bushings is how easy they are to install - simply slide them in place during your bushing install. They can be added to pre-installed bushings too by dropping the trailing arm and removing the cage around the bushing.

Works with stock rubber bushings only (not urethane or Delrin).

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved acceleration response, more direct shifting feel and overall improved drivetrain composure with Powerflex performance polyurethane bushings.

Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle.

These camber plates are perfect for the enthusiast owner who wants a high quality design with a motorsports background. Knowing a full race kit on the street is not often the best option, we took the best features from the Race Camber Plates and incorporated them into a fresh Street design -

  • preserves the correct E46 M3 geometry
  • separate sliding camber and caster adjustments
  • maximum shock travel
  • light weight
  • durable materials
  • large surface area
  • ease of use

The Turner E46 M3 Street Camber Plates are the most advanced design on the market. These are designed specifically for the E46 M3 - no shortcuts or cookie-cutter components. We started with a fresh design to make these very user friendly and easy to install and set up. The E46 M3 front suspension has unique geometry and the strut is mounted at an angle that can put significant side loading on the strut shaft if it's not located properly. The location and angles for the main bearing were carefully engineered to allow the proper motion ratio and strut angles during adjustment. This greatly reduces bending forces on the strut itself which improves performance and longevity. By designing for one chassis we're able to focus on what works best in that application - proper fitment and operation without unnecessary adapters, easy-to-use camber and caster adjustments, and an intelligent modular design.

For street use we added a pliable urethane bushing to absorb vibration and a special base design that works with the factory radial bearing and spring perch. The radial bearing allows the spring to rotate instead of twisting and binding. By re-using the factory radial bearing we can keep the assembled stack height lower for maximized shock travel. It's also a commonly-available item that you can get from any BMW dealer at a low price. All of the things that make it work well in the factory application carry over to our design. You can use our camber plates with a stock sized spring, 60mm, or 2.5" springs. Use your stock spring perch/bearing with stock-sized springs. The 60mm and 2.5" upper spring perches are sold separately. The beauty of our design is that you can use the factory radial bearing with any of these springs.

Another important feature of the Turner Camber Plates is the size of the upper plate. Our plates have a very large surface area to better spread strut forces through the strut tower. A smaller upper plate, like those found on competitor's kits, will localize strut forces and contribute to strut tower deformation ('strut tower mushrooming'). This is a very important feature especially as these cars get older and spend more time on the track. Deformed strut towers are a serious performance and safety concern and our camber plates are properly designed to handle the loads. The factory strut reinforcement plates are not required with our camber plates (but you can use them if you want to).

Since this design is specific to the E46 M3, we can build it with the bare minimum of adapters and extra hardware. This not only cuts down on confusion but makes it easier to assemble and operate. We use the correct-sized bearing for the 16mm strut shaft; no sleeves or bearing adapters required. The original tapered lower mount support and a small stainless steel spacer from our kit are all that's required to install. We have used our camber plates with most of the major strut manufacturers on the market - stock Sachs/Boge, Bilstein, Koni, H&R, ST, and KW. Our camber plates work with any strut that is designed to accept the factory strut mount.

Rear Axle Carrier Panel (RACP) failure is a well-documented issue that plagues all BMW E46 models. Due to thin sheet metal mounting, the forces applied during cornering, acceleration, and braking create stress fractures in the carrier panel, resulting in large cracks or breaks that risk the structural integrity of your chassis. To fix this issue, many enthusiasts opt to install weld-in reinforcement plates on the underside of the RACP. While this remedies the formation of additional stress cracks and adds rigidity to failure-prone areas, it does not prevent the entire carrier panel from flexing during high-performance driving.

Our all-new Rear Subframe Reinforcement Brace is engineered to add structure to the E46's rear chassis under high-stress conditions, eliminating the common weak points in the RACP while providing the confidence you need for performance driving. Don't let chassis flex limit your car’s potential—upgrade your E46 with the Turner Motorsport Rear Subframe Reinforcement Brace today!

How It Works:

During performance driving, the Rear Axle Carrier Panel (RACP) must react the forces of longitudinal and lateral accelerations. During forward acceleration, the differential transmits torque through the subframe to the RACP, forcing the rearmost subframe mounting points downward. This downward movement flexes the carrier panel, reducing its ability to handle torque efficiently. By linking the rearmost subframe mounting points to the rear shock towers, downward flex is restricted, resulting in improved torque transfer and stability. Alternatively, high-grip cornering generates lateral acceleration (side-to-side) forces across the RACP. Similar to how a rear strut brace functions, connecting the rear shock towers helps to counteract these forces. Adding the subframe to this connection further reduces lateral loads, eliminating side-to-side flex and enhancing overall stability.

Features & Design:

Four-Point Triangulated Structure: Links the rearmost subframe mounting locations to both rear strut towers for superior load distribution. Enhanced Stability: Reduces lateral and longitudinal RACP flex during acceleration, braking, and cornering. Improved Torque Transfer: Minimizes downward flex of the RACP, ensuring efficient power delivery for enhanced driveability. High-Performance Durability: Heavy-duty steel tube construction ensures lasting support during spirited driving, track use, and for vehicles with increased power output. Blue Powdercoat Finish: Offers fantastic corrosion resistance, protection from scuffs and scratches, and a stylish appearance that is sure to complement your performance-centric E46. Underside Reinforcement Compatibility: Designed to work seamlessly alongside our underside RACP reinforcement plates (TDR4675412, T#91). Kit Includes:

Rear Subframe Brace Sedan Subframe Brace Spacers Extended-Length Drill Bit (1/4", 12" Overall Length) High-Speed Drill Bit (12.5mm, 152mm Overall Length) Drill Bit Guide Extended Subframe Bolts Zinc-Plated Steel Hex Nut (2) Installation & Support:

The stock Genuine BMW rear lower wishbone control arms (33326770813) are great for standard daily driving and occasional spirited driving, but they tend to fall flat on the track due to the soft rubber bushings causing excess deflection, creating undesirable handling characteristics. In order to address this issue, Turner now offers new Performance Rear Camber Arms (V2) with upgraded FK Spherical Bearings! These camber arms offer multiple benefits over the stock control arms, helping to keep your BMW under control and on the track. The upgraded Turner camber arms offer an increased range of rear camber adjustment, necessary for lowered cars and performance alignments to maintain proper rear camber and reduce tire wear on the street and track. This provides increased stability and predictability to the rear suspension for tighter handling. These camber arms feature gun-drilled 2024 Aluminum center links, clamps, and clevises, along with a 360-degree rotating clamp system. This combination provides superior strength, performance, durability, and ease of adjustment. No annoying jam nuts! A simple 3/16" Allen-key is all that is required to lock down your alignment settings. FK Spherical Rod Ends are utilized to reduce alignment change in the rear suspension under hard cornering, acceleration, and braking. They feature a Teflon liner to provide quiet operation, low friction, smooth articulation, and eliminate bushing deflection under load. The PTFE liner is chemically bonded to the inner diameter of the race, offering a very high load carrying capacity and greatly increased dynamic wear characteristics. This results in robust reliability for and track use!

Rear trailing arm bushings serve the key purpose of keeping rear suspension triangulated and the vehicle moving where it's directed to. Though failure prone, even factory-fresh OEM rubber bushings allow for deflection, causing suspension geometry changes on hard launches, over bumps in the road, and during cornering. This deflection results in clunking in the rear end, a “rear steer” feeling, and uneven tire wear.

Powerflex polyurethane rear trailing arm bushings are firmer than OEM bushings, resulting in a reduction of deflection that causes these suspension angle changes, improving handling over bumps and with a proper alignment, extending tire wear.

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings. Expect improved steering feel, turn in, more responsive handling and overall improved chassis composure with Powerflex performance polyurethane control arm bushings.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

Control arm bushings play a key role in connecting the wheels to the chassis of the vehicle. Tasked with keeping suspension geometry in check while absorbing noise, vibration, and harshness (NVH) factory rubber bushings were engineered to provide a balance of comfort and control. As a factory bushing ages, it becomes brittle and begins to harden. When this happens the bushing will actually shrink and allow excess play in the suspension joint. This is typically felt by a sudden jerk forward after the car comes to a stop and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushing with a full polyurethane unit or using a bushing insert, this play is eliminated since the suspension joint is being supported by a much stiffer material that will not harden or shrink over time. Additionally, the inherent stiffness of the urethane material translates body forces much more directly. This means steering inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver.

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.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Differential bushings are responsible for keeping the differential in solid alignment while dampening drivetrain vibration. While OE rubber bushings are fine when they are new from the factory, aged and worn out rubber bushings create a multitude of issues that can range from annoying to dangerous. As a factory bushing ages, it begins to harden and become brittle. When this happens the bushing will actually shrink and allow for movement at the differential mounting point. At this point, the differential is free to shift under load causing a noticeable clunking noise under acceleration and deceleration and massively increasing the stress on the driveshaft and axles. Manual transmissions suffer the worst from this as it can make shifting difficult since the differential will shift when the clutch is engaged and disengaged.

By replacing these bushings with full polyurethane, the movement is eliminated since the mounting point is supported by a much stiffer material that will not harden or shrink over time. This means less stress on the driveshaft and axles and greater longevity of supporting components. 

Powerflex Black Series bushings are the ultimate in track and race bushings. Featuring 95A durometer polyurethane, Black Series bushings are 25% stiffer than street bushings. Engineered to perform, Powerflex performance polyurethane control arm bushings offer a supreme level of control, while still providing enough comfort for the street, with advanced polyurethane that reduces NVH that often accompanies lesser bushings.

Any subframe work or reinforcement project on the rear of the E46 M3 should include a new set of subframe mounts. It's the worn rubber bushings that contribute to failed rear subframes on the E46 (but not the only reason). As the rubber gets worn, there is more flex to the mount. This flexing is then transferred to the sheetmetal in the floor where the spot welds will pop and the sheetmetal will crack. Additional force coming from stiffer suspensions and stickier tires will only increase the flexing of the mounts/chassis.

Of course, stiffer mounts would help prevent this problem but with a stiffer bushing comes ride harshness, vibration, and additional noise. Our engineers and technicians recommend replacement with the factory rubber bushings (along with the appropriate reinforcement of the floor).

Bilstein has teamed up with Eibach to offer matched shock and spring packages. These Eibach springs are mated to a special set of Bilstein shocks to deliver a sporty and taut ride with as little impact on ride comfort as possible.

The Pro Kit uses an Eibach Pro Kit spring with Bilstein's Sport shocks and struts. Instead of taking parts from different manufacturers, Bilstein has tested the performance of the Eibach spring and tailored their shocks to be a true match for the new spring rate and ride height. This is known as a matched shock and spring and very few tuning companies take these extra steps. Eibach springs tend to be softer overall than most other aftermarket springs, which ensures the ride stays close to a stock comfort while still giving you a lowered stance and improved handling. 

Bilstein B12 Features: 

  • Precise response and excellent driving performance
  • Springs and shocks road tested and fine-tuned to complement one another
  • Bilstein Monotube/Inverted gas pressure technology
  • TUV certified
  • Made In Germany
  • Average Lowering of 25 to 40mm

Most cars don't need coil overs to improve their handling and bodyroll. For most drivers, simply replacing the shocks and springs with performance versions will meet their goals. If your shocks need replacing, and you felt the handling could be improved a little bit, this is an excellent performance suspension for you.

This item fits the following BMWs:
2001-2006 E46 BMW M3

Our Rod-End Camber Arms deliver the ultimate in precise camber adjustments and a free-motion design, thanks to the finest rod-end bearings available. We use high-quality stainless, PTFE-lined bearing joints made by the best manufacturers in the business. These bearings are self-lubricating with a PTFE fabric liner for long life and quiet operation. The bodies and threads are heat treated stainless steel. Without spending hundreds of dollars per bearing, these are the best on the market.

Over time, and depending on use and application, the bearing can develop play which does not adversely affect the performance but will make a "clicking" noise. We have a spec tolerance of .015" before recommending replacement. The bearing itself will continue to rotate freely and the camber arm will function as normal. But should you want to replace the rod-end because of the noise, or to meet track inspection requirements, we offer this replacement end. As far as we know this rod-end fits only our BMW rear camber arms and no other brand, although it may have other applications. Price is per rod-end.

The upper rear shock bolts to the sheetmetal in the folding top well on convertible models. As the mileage goes up more and more stress is put on this sheetmetal and it can actually tear away from the rest of the chassis. Look for lttle cracks originating from the mouning holes. This reinforcement plate helps spread the shock loads around the sheetmetal and reduce stress in localized areas. Price is for the pair.

Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This in turn reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

The rear springs on the 2001-2006 E46 M3 models have a chronic broken spring problem. If it hasn't happened to you yet it will. Springs are nothing more than exposed steel and they rust easily. After a while a section of the spring actually breaks off.

A broken spring is very dangerous - the spring is no longer mounted correctly in the suspension and it cannot support the weight of the car, especially when cornering. The ride also suffers as the suspension is no longer able to absorb the bumps and impacts from the road. Aside from a visual inspection of the spring itself you might notice a clunking sound or banging noise coming from the front or rear. An inspection of the noise should also include other related items in the suspension: bushings, ball joints, links, mounts, etc. We also recommend replacing the rubber spring pads on the top and bottom of the spring because they lose their shape over time.

The factory BMW springs sell for $140+ each. We sold and replaced enough while working in New England that we were able to get a strong grasp of the issue and come up with our own springs that are an improvement over the factory springs in every way. These springs are made in Germany using high grade spring steel that is then shot-peened for longer life and powder-coated for protection. These are the same height as the stock replacement BMW springs which makes them a direct replacement.

Replaces Coupe models only.
