BMW E46 Turner Motorsport Front Control Arm Performance Kit: Upgrade Your BMW's Handling

  • Improves handling and steering response
  • Enhances cornering stability and control
  • Reduces flex and play in the front suspension
  • Durable construction ensures long-lasting performance

Enhance the performance of your BMW with the BMW E46 Turner Motorsport Front Control Arm Performance Kit. This kit is designed to improve handling and steering response, providing a more dynamic driving experience. With enhanced cornering stability and control, you'll feel confident taking on corners and curves. The kit also reduces flex and play in the front suspension, resulting in improved overall handling characteristics. Plus, its durable construction ensures long-lasting performance, making it a reliable upgrade for BMW enthusiasts.

When you're looking for a control arm upgrade for your M3 this Turner Motorsport package is unrivaled, featuring their popular monoball bearing to replace the failure prone rubber bushing. The upgrades for this product aren't only that they will outlast everything else you can put on your car. These monoballs offer much smoother, more responsive steering that allows the front control arm to articulate more naturally instead of fighting against the suspension causing deflection.

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 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:

  • Paired with Lemforder control arms
  • Made in America

Bearing

- Extremely robust, grease-able, 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.

Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) factory rubber subframe bushings were engineered to provide a balance of control while keeping the ride quality soft and supple. As a factory bushings age, they become brittle and begin to harden. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place 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 and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver. 

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? 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.

For BMW E46 (3 Series), Z4, and X3, upgrading to Powerflex rear subframe rear bushings is an effective way to improve the durability and handling of the suspension system. Powerflex polyurethane bushings are a popular upgrade over the factory rubber bushings, offering enhanced performance and longevity, particularly for cars used in performance driving or that are susceptible to subframe wear.

Features and Benefits of Powerflex Rear Subframe Rear Bushings:

  • High-Performance Polyurethane Material: Powerflex bushings are constructed from polyurethane, which is significantly more resistant to deterioration than rubber. Polyurethane is less affected by elements like heat, road debris, and oils, ensuring that the bushings maintain their performance characteristics for much longer.
  • Enhanced Handling Precision: One of the primary benefits of polyurethane bushings is reduced subframe movement. By replacing the flexible rubber bushings with stiffer polyurethane versions, you’ll experience sharper handling, more precise suspension response, and improved chassis control, especially during hard acceleration, cornering, and braking.
  • Reduced Subframe Flex: The rear subframe is subjected to significant forces, particularly under high-performance driving conditions. Powerflex bushings help reduce the flex that can occur in the subframe, keeping the rear end more stable, improving vehicle control, and enhancing cornering performance.
  • Longevity and Reliability: Powerflex bushings are engineered to outlast the stock rubber bushings by a significant margin. They are designed to endure the demands of high-performance driving without deteriorating, which leads to fewer replacements over the life of the vehicle.
  • Optimized NVH Balance: While stiffer than rubber bushings, Powerflex designs its bushings to minimize the increase in noise, vibration, and harshness (NVH). This ensures that the bushings provide improved handling without compromising ride comfort, making them suitable for daily drivers as well as performance-focused cars.

Installation Considerations:

  • Direct Replacement: Powerflex bushings are manufactured to be direct replacements for the factory bushings, meaning they fit into the stock locations without modification. However, accessing the rear subframe for installation can be a complex task, often requiring the subframe to be dropped, so professional installation is recommended.
  • Subframe Reinforcement: For vehicles like the BMW E46, known for rear subframe cracking, many owners choose to upgrade their bushings alongside subframe reinforcement plates. This combination helps prevent the stress fractures that can occur in the mounting points.

Applications:

  • BMW E46 (3 Series)
  • BMW Z4 (E85/E86)
  • BMW X3 (E83)

Suitable For:

  • Daily Driving and Performance Use: Whether you're using your BMW for spirited street driving or taking it to the track, Powerflex rear subframe rear bushings provide improved handling and stability without significantly increasing NVH.
  • Subframe Longevity: If your car is prone to subframe issues or you want to take preventive measures, upgrading to these bushings will help reduce the wear on critical suspension components, extending the life of the subframe and related parts.

By upgrading to Powerflex rear subframe rear bushings, BMW E46, Z4, and X3 owners can expect improved handling, reduced subframe flex, and longer-lasting suspension performance, making it an ideal upgrade for both street and track use. These bushings strike a great balance between enhancing performance while maintaining daily driving comfort.

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.

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.

Tasked with keeping the vehicles rear end firmly mounted while absorbing noise, vibration, and harshness (NVH) factory rubber subframe bushings were engineered to provide a balance of control while keeping the ride quality soft and supple. As a factory bushings age, they become brittle and begin to harden. When this happens the bushing will actually shrink and allow excess play, or movement in the subframe. This is typically felt by a sudden jerk or "thunking" noise under acceleration and is a leading cause of "sloppy" or "loose" suspension feel. By replacing the bushings with full polyurethane this play is eliminated since the subframe is being held in place 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 and acceleration inputs from the driver are effectively transferred to the wheels and vital road information is transmitted properly from the wheels to the driver. 

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? 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 a "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.

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.

Upgrade your vehicle's handling performance with Powerflex polyurethane sway bar bushings. Unlike OEM rubber bushings that prioritize comfort over precision, Powerflex bushings are designed to reduce body roll and enhance cornering confidence.

Sway bars play a crucial role in transmitting cornering forces from the outside wheels to the inside wheels, ensuring your vehicle stays flat during sharp turns. However, OEM rubber bushings can lead to unnecessary body roll due to their flexible nature, compromising the effectiveness of the sway bars.

Powerflex polyurethane bushings offer a firmer alternative to OEM rubber, providing improved bar retention and minimizing sloppiness during cornering. This results in enhanced handling capabilities and a more engaging driving experience.

As the leading suspension bushing manufacturer in Europe, Powerflex leverages its expertise in polyurethane materials and advanced manufacturing techniques to produce premium bushings that meet exact-fit standards. Whether you're driving on the street or hitting the track, Powerflex bushings are built to last longer than OEM rubber counterparts while delivering superior performance.

For easy installation and prolonged service life, we recommend using Powerflex Copper Grease PCG1. This grease helps reduce squeaks and ensures optimal performance of the bushings over time.

Choose Powerflex street bushings for daily-driven vehicles with occasional autocross or track outings. For dedicated track cars seeking maximum stiffness, Powerflex Black Series bushings with a 95A durometer polyurethane material are the ultimate choice, offering 25% more stiffness than street bushings.

To top it off, Powerflex stands behind its products with a lifetime warranty for the original purchaser, providing peace of mind and assurance of quality and durability. Upgrade your suspension with Powerflex and experience the difference in handling performance.

Condor's Offset Rear Trailing Arm Bushings (RTABs) are perfect for the street and the track. They're designed to help correct rear toe-in and toe-out issues on lowered cars. To correct for toe-in: RTABs can be installed with the thick side inboard to help push the rear trailing arms towards the outsides of the car. To correct for toe-out when running minimal camber setup: RTABs can be installed with the thin sides inboard to help push the trailing arms inwards. The amount of total adjustment is purely dependent on how low your car is, but we've seen toe adjustment from 1/8” out on each side to 1/8” in on each side, which is a super nice range for the e36 rear end! They use UHMW in all of their suspension bushings because it is self-lubricating, meaning it requires no grease when installing, has almost zero deflection yet also absorbs some vibration. It will outlast other types of rubber or urethane bushings. They include black oxide plated steel plates for each RTAB to prevent lateral movement between the bushing material and the aluminum. Polyurethane and rubber bushings will deflect and slide, causing your rear alignment settings to change mid-corner. With these bushings, you won't have to worry about dynamic changes in your toe settings; the rear alignment stays in check during hard cornering, braking, and acceleration. This item fits the following BMWs: 1992-1998 E36 BMW 318i 318is 318ic 323is 323ic 325i 325is 325ic 328i 328is 328ic M3 1999-2005 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi M3 2003-2008 Z4 BMW Z4 2.5i Z4 3.0i Z4 3.0si Z4 M Roadster M Coupe Kit includes a pair of trailing arm bushings

This aluminum spring seat fits between upper and lower 60mm springs to "join" them together. Typically you would have a main spring on top and a tender or helper spring on the bottom (or vice-versa). The spring joiner, or locator ring, fits between the springs with a retaining lip on the inside. We like this design better than an outside spring joiner because it's lighter and there's no material sitting on the outside where a tire might come in contact with it. These are priced per each.

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.

Powerflex street bushings are ideal for street driven vehicles and those that see occasional autocross or track time. Need bushings for a dedicated track car? 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 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.

Reinforces the strut towers against deformation while adding valuable triangulation to the front end for sharper, more predictable handling. Designed to prevent “mushrooming” and other distortion caused by rough roads or stiff suspension setups, these plates help maintain consistent suspension geometry by reducing unwanted chassis flex. The result? A more stable, confidence-inspiring front end under load. Strut tower plates are engineered to sit perfectly flush against the towers. If they don’t, it’s a sign the towers have experienced some deformation. In minor cases, this can often be corrected using a block of wood and a hammer to carefully restore the mounting surface.
