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 renowned TMS adjustable front sway bar / swaybar links for BMWs are now available in custom lengths, making them easy to order for any aftermarket or custom suspension setups. Simply measure for your ideal link length, and order the links with the best length range (below). Each sway bar link has a 10mm diameter mounting pin/stud, which is the typical factory/stock size for a universal fitment. These are sold by the pair, and each set includes two matching sway bar end links.
These end links offer the quiet operation and long life of "stock" BMW end links, but with the strength and adjustability of rod-end style sway bar links. These sway bar links can be used on a wide variety of BMWs and aftermarket BMW suspensions. When measuring, please consider that the length ranges of our Custom Adjustable end links are measured from the center to center on the end link mounting stud / pin, as shown in our diagram.
Note for E9X M3: the unique mounting on the M3 strut requires a set of our adapter seats (#TSU9912AF9). You can add them with your links from the menu below.

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.

You get the best of both worlds with this pair of Turner Motorsport adjustable sway bar links. We searched far and wide to find the hidden gem of swaybar links. You get the same quiet operation and long life as the stock links plus the strength and adjustability of rod-end style sway bar links.
With the wide range of suspensions and sway bars available today adjustable sway bar links can help you with many problems. Along with the ability to remove preload you can change the length to maximize sway bar geometry. Example: if the sway bar hoop comes too close to the steering rack, oil cooler, or under tray in its suspension travel you can adjust it by simply lengthening or shorting the adjustment rod. In some cases you may need a longer or shorter adjustment rod to achieve optimal geometry. We also offer these same links in other custom lengths (click here) that may not be specific to BMW chassis.
