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.

Top seller! The Turner Adjustable Rear Camber Arms: The Only Adjustable Arms Approved for Grand-Am Continental Tire Challenge Racing Series Why you should use Turner Motorsport camber arms on your car: If you have a lowered car and have run out of adjustment with the stock camber arms. If you have a track car and are looking for increased camber adjustment, lightweight pieces, stronger components, and improved suspension handling Two bushing styles to meet your needs: solid rod-end for track-only use (See T#304098), or rubber bushing for mixed street/track use (approved by Grand-Am!) The high range of adjustment allows a full racecar setup or a heavily lowered car to maintain factory specifications. Only high quality and high strength materials and components are used Aluminum camber arms are designed as a lightweight component, thereby reducing wear and tear on other, more critical parts (rear subframe, control arm bushings, etc). Each camber arm weighs only 2.5 lbs making for a total of 5 lbs for both parts! Stock camber arms weigh 3 lbs each. We have seen competitor's arms that weigh twice as much! Hardcoat anodized aluminum, stainless steel turnbuckles, and stainless rod ends to all but eliminate corrosion from getting into the threads and making adjustment difficult. CNC-machined double shear design for ease of installation, high strength, and choice of outside bushing material. But we do suggest using with (outer bushing # 33326775551) for best performance. Easy adjustment - our main adjustment point is on the outside by the wheel so there is no need to work around the exhaust or subframe to adjust camber. All hardware included. Installation Instructions: Instructions for Bushing-End Style (TSU9940B77) This item fits the following BMWs: 1992-1999 E36 BMW 318i 318is 318ic 323is 323ic 325i 325is 325ic 328i 328is 328ic M3 1999-2006 E46 BMW 323i 323ci 325i 325ci 325xi 328i 328ci 330i 330ci 330xi M3 2001-2006 SpecE46 BMW 330i 330ci 2003-2008 E85 BMW Z4 2.5i Z4 3.0i Z4 3.0si Z4 M Roadster M Coupe

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.
