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.

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.

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.

E36/E46/Z4, including M models, rear lower control arm (camber arm, wishbone). This is a direct replacement for the stock arm and includes the inner bushing. These arms are designed to be slightly weak and flimsy as they will absorb impact energy. It's better for this arm to absorb an impact rather than the wheel or trailing arm, or subframe, etc. Also, unknowing tow truck drivers like to use this part to hook their chains on to. Consequently they bend as easily as a coat hanger. An OEM replacement from Lemförder is the perfect option to restore control and suspension quality.

The front control arm bushings are a key piece of the suspension. They are constantly in motion and take abuse from impacts, potholes, rough roads, and general cornering/wheel motions. To give a quiet and smooth ride, the bushings are made of rubber with a metal sleeve insert. But the rubber can only withstand so much abuse before they become loose and spongy. This results in vibrations and possibly a shimmy when driving. A visual inspection will usually confirm that there is too much flex in the rubber or the rubber has cracked and torn. And if you're installing new control arms, always install new bushings to avoid duplicating labor costs.
This is a replacement stock RIGHT FRONT (Passenger's side) control arm bushing with the mounting bracket.

This E36 or Z3 front control arm is a direct replacement for the original part and is the OEM Lemforder brand.
Control arms, and their integrated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.
We also recommend replacing the bushings when changing the control arms. The bushings are mounted at the back of the control arm and located the arm to the frame rail on the car. The stock bushings are rubber and will wear out sooner than the control arms themselves. With the control arm off the car now is the perfect time to also replace the bushings.

Here at Turner we understand the importance of an upgrade that will get the results you need on the track and still be tolerable on the drive around town. When it comes to control arms on the track, making them as stiff as you can (usually using solid mounts) is the best way to increase your driving precision by eliminating the deflection of rubber. The next best thing to create a balance would be to stiffen up the control arm with polyurethane, giving you the option of a more stock like feel with 80a or closer to the solid feel with 95a durometers. These poly bushings will give your control arms a direct connection between your suspension and the body of the car eliminating the slop felt under take-off and braking so you feel more in control of your vehicle.
Already pressed into bracket so you can get right to the install.
*Featuring a delrin sleeve to eliminate heat deformation and premature failure.

This control arm upgrade was used on the high-performance 330i ZHP Performance Package and offered by BMW as a sport retrofit. These arms are identical dimensions as the regular arms so they are a direct replacement. But they have all metal ball joints instead of plastic or rubber. This means they last a lot longer and are much stronger. We used these in our Grand Am and World Challenge E46 racecars with excellent performance.

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.

When it comes to control arms on the track, making them as stiff as you can (usually using solid mounts) is the best way to increase your driving precision by eliminating the deflection of rubber. The next best thing to create a balance would be to stiffen up the control arm with polyurethane, giving you the option of a more stock like feel with 80a or closer to the solid feel with 95a durometers. These poly bushings will give your control arms a direct connection between your suspension and the body of the car eliminating the slop felt under take-off and braking so you feel more in control of your vehicle.
*Featuring a delrin sleeve to eliminate heat deformation and premature failure.
This item fits the following BMWs that use a centered-style bushing:

OEM Lemforder front control arm bushings as used on the E46 325i, 330i, and Z4 and an upgrade for the E46 323i and 328i. These are the upgraded 66mm bushings used to eliminate vibrations in the early E46 front suspension. The front control arm bushings are a key piece of the suspension. They are constantly in motion and take abuse from impacts, potholes, rough roads, and general cornering/wheel motions. To give a quiet and smooth ride, the bushings are made of compliant rubber. But the rubber can only withstand so much abuse before they become loose and spongy. This results in vibrations and possibly a shimmy when driving. A visual inspection will usually confirm that there is too much flex in the rubber or the rubber has cracked and torn. And if you're installing new control arms, always install new bushings to avoid duplicating labor costs.
These bushings come pre-pressed into their aluminum brackets. No need to press out old and press in new bushings! Just a simple swap! Price is for the pair.

This E46 325Xi/330Xi front control arm is a direct replacement for the original part and is the OEM Lemforder brand. The E46 Xi front control is a special design borrowed from the E34 525Xi (sold in Europe) but still similar to other E46 cars. Therefore, it still suffers the same ball joint issues as the other 3-series models.
Control arms, and the associated ball joints, are some of the most crucial components on a BMW suspension. The control arms literally control the wheel and suspension as they go through their range of motions. A faulty or worn control arm or ball joint is a very dangerous and potentially life-threatening problem so make sure they are inspected and replaced at regular intervals. For a street-driven car we advise yearly inspection and a full replacement every 3-4 years. For track-driven cars these should be inspected before every event and replaced every two years.
On the Xi we also recommend replacing the inner ball joints and rear bushings when changing the control arms. The ball joints are designed to be replaced separately and the bushings are mounted at the back of the control arm. Both are high-wear parts and easily replaced with the control arm off the car.

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:
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.
- Improved road feel without undesirable NVH.
Grease before installation and with each oil service with high quality Moly grease for maximum service life. Grease fitting tool - ES#3410138

We also recommend replacing the bushings when changing the control arms. The bushings are mounted at the back of the control arm and located the arm to the frame rail on the car. The stock bushings are rubber and will wear out sooner than the control arms themselves. With the control arm off the car now is the perfect time to also replace the bushings.

Factory bushings are more than adequate for street driving on the E46 M3. However, once the miles start to pile up, the bushings are meant to be replaced. Common side effects of worn factory FCABs include, but are not limited to the following:
Replacing with new factory bushings will return the factory feel. These urethane core bushings, however, offer something MORE. These bushings are designed to deliver performance that surpasses the stock E46 M3 bushing, while still allowing them to be used in everyday driving scenarios on public roads.
With the numerous delrin/urethane/hybrid replacement bushings in the market, we wanted to offer bushings that were not only effective, but simple. No clips, no washers, no multiple sleeves, and no "race parts in street cars". They have an aluminum outer sleeve with a replaceable, compliant urethane core that is serviceable and rebuildable. These urethane inserts prevent unwanted control arm deflection, while allowing noise/vibration/harshness (NVH) isolation -- a must on any bushing being used on a street driven car. And because of their compliance they remain very comfortable for daily use. But because they are a heavier-duty design than stock, these eliminate steering shimmy and wander, especially with the addition of big brake upgrades. They maintain BMW's original suspension geometry, and give your M3 a directly "connected" feeling with the front end of the vehicle. Perhaps best of all, these bushings are easy to install and are designed for longevity. Professional installation on suspension components is always recommended.
