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.

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.

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.
This item fits the following BMWs that use a centered-style bushing:
