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.

Features:

Made in the USA The rear subframe is the heart of the BMW rear suspension. Not only do all of the suspension arms attach to it, the driveline runs through it via the differential and half-shafts. Therefore, a track-prepped E46 should never see any flex or deflection in any of the subframe mounts. Excessive movement here transfers to unwanted suspension motions elsewhere and is also a major contributor to failures in the rear floor sheetmetal.

While our Delrin-Aluminum subframe mounts conform to various racing series these all-aluminum mounts are the ultimate in reducing flex and deflection. The rubber stock mounts, and the Delrin mounts to a small degree, flex and deflect as various forces are applied throughout the subframe - on and off throttle loading, cornering on flat surfaces, bumpy surfaces, weight transfer, sticky race tires, etc. Too much flex from worn rubber mounts will transfer to flex where the subframe meets the chassis/floor. This is the primary cause for the infamous rear subframe failure. These fully solid aluminum mounts have absolutely zero flex to them so they will not contribute to rear subframe issues. The Turner E46 Reinforcement Kit is still recommended.

These solid subframe mounts were designed for racing use only, where we won several sports car championships in the Grand-Am Cup series. These subframe mounts are over-engineered to be a major improvement over the stock subframe mounts not only for performance but also in strength as well. The aluminum is CNC machined for a precise fit and minimal weight. One front bushing is slotted to allow for BMW's manufacturing tolerances. Professional and experienced installation is required.

Made in the USA Want the Ultimate design in a rear shock tower mount? You've found it. These rear shock mounts are designed for use on the track and racing. This set of mounts will help your rear shocks perform the best they can in those conditions. The advantage to using a mount with spherical bearing is that it allows the shock to freely move off axis without side loading the shock shaft like rubber or polyurethane mounts do. Side loading a shock increases stiction and wear which decreases its efficiency. Because these are mounts without an isolator (rubber or polyurethane) to dampen road noise and vibrations we do not recommend them for street cars. These were designed in-house and developed for our own track and race cars.

These TMS bearing mounts include both 10mm and 12mm stainless steel bearing sleeves to work with a wide variety of shock shaft pins. The pin is the upper-most portion of the shock where it passes through the mount. If you need a bearing sleeve size other then 10mm or 12mm please contact us.

These rear shock tower mounts fit the following BMWs:

Turner Motorsport Bushing Limiters were the first - and still the best - RTAB Limiter on the market. Instead of a 'floating' design that can rattle and wear, our aluminum Limiters are fixed in place and feature an anti-stick Teflon coating so the bushing never sticks and squeaks.

The great defect in the rear trailing arm bushing (RTAB) is that the soft rubber design allows too much movement and extension during cornering. The bushing is not strong enough to resist hard cornering loads. A stiffer bushing helps but has trade-offs in ride and comfort. If you want to maintain your ride comfort with rubber bushings, these RTAB Limiters will prolong their life and improve handling.

These Limiters sit on either side of the bushing and limit its movement. By limiting motion the bushing effectively becomes stiffer, improving handling and reducing toe change during cornering. When not cornering, the Limiters are not in play so ride comfort remains the same as stock. Our Limiters are permanently bolted to the housing that surrounds the bushing. Other types of Limiters 'float' between the bushing and housing, which can rattle and squeak as the bushings move. Instead of plastic or Delrin that will wear over time, our RTAB Limiters are made from aluminum with a tough hardcoat anodize (tougher than standard anodizing) and finished with a Teflon anti-stick coating.

Turner RTAB Limiter Kit includes -

  • set of 4 anodized aluminum bushing limiters
  • 5mm Allen bolts and washers
  • install template

Made in the USA If you haven't already upgraded to Adjustable Camber Arms , your stock rear lower wishbones are letting your down. The stock rear camber arm/wishbone is designed to be flexible and weak. In an impact, it's designed to bend or even break to absorb energy and prevent damage to other more vital components. This is great on a regular street car. But on a track car, or heavily modified street car, these arms can bend just from cornering forces and that can introduce radical camber changes that will throw off the balance and handling of the car. This reinforcement solves all of that by tying the two sections of the arm together. This creates a single solid arm with minimal flex in the arm itself. We can't take credit for this innovation - BMW recognized the problem and did this on their factory Group N racecars. If you haven't made the jump to adjustable arms, or your racing class still requires the stock camber arm, then this kit is a must! Installation requires welding.

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).

This ball joint is used for the upper rear trailing arm bushing on ALL E36, E46, E83 X3, and E85 Z4 cars. BMW also used it as the lower bushing on most M cars. It makes a great upgrade on all non-M cars where BMW used a rubber bushing at the lower position.

This sealed ball joint is one of the best things about the rear suspension - it functions extremely well and lasts a long time. And it can be used as a replacement for the existing bushing without any further modification. The non-M cars used a solid rubber bushing for the lower arm (camber arm, wishbone) which does not last very long and relies on bushing deflection (twist) during suspension motions. The ball joint inside the upgraded design is much more effective during this suspension movements as it does not bind or deflect. And because it's sealed with rubber it will last a long time and remain quiet and maintenance free. Most customers report that after installing or "upgrading" to these bushings the rear end of their car felt much more stable.

Price is per bushing. Left/Right and Upper/Lower are the same part.

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.

The upper strut mount provides a locating point for the top of the front struts. It contains a rubber-isolated bearing that allows the strut shaft to move independently from the rest of the suspension - a critical component for the suspension to be quiet and effective. The rubber also absorbs vibrations and impact harshness, helping to keep unwanted noise and harshness from reaching the steering wheel.
