Rear Control Arm

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.

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).

The stock Genuine BMW rear toe links (33322284534) 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, not to mention insufficient adjustability.

Turner's new Performance Rear Toe Links increase stability and response by eliminating bushing deflection while providing an increased range of rear toe adjustment, necessary for lowered cars or for performance alignments. Even small changes to ride height and camber will effect toe settings, and the wide range of adjustment allows you to maximize grip on a track car and extend tire life on a street car. The factory rear toe arms utilize an eccentric bolt and washer for adjustment and lack precision and range.

These toe links 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. Best if tightened to 73.7 ft. lbs. (100 N/M). DO NOT OVERTORQUE! ECS is not liable for any issues due to overtorque.

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.
