The ORIGINAL rear trailing arm bushing / RTAB shim kit -- and still the best! The Turner rear trailing-arm bushing limiter kit creates a stiffer rear suspension without sacrificing ride quality. Stock trailing arm bushings are known for failure, on both the E36 and E46 BMW chassis. This kit is a perfect upgrade from stock, as it reduces bushing deflection, dramatically increases bushing life, improves handling, and all without the harshness of "race-only" bushings, and while maintaining completely silent operation -- no squeaks and no vibration, whatsoever.

By combining these limiters with stock bushings, this is a great low cost and effective suspension performance enhancer. Each pair of blue aluminum "shims" essentially sandwich the stock rubber bushing to control their lateral movement. By limiting the amount of side-to-side play of the stock bushing, drivers will have increased driver feel thanks to the reduction of toe variation caused by the squirm of the stock rubber bushings. This also reduces duress on the bushing, giving your newly installed bushings a dramatically longer lifespan (a welcome benefit for both pure street or tracked cars). Some stock class racing series even allow this kind of modification, because the stock bushing is still being used.

Kit includes: 4-Blue anodized aluminum bushing limiters, eight 5mm allen bolts and a drilling template.
