BMW E85 Chassis Reinforcement Kits & Parts
Most of our kits are not labor intensive although welding is usually required. If you suspect your chassis may have structural problems we recommend taking it to a well-known bodyshop or restoration shop. (find out who your local BMW dealer uses - we sell many of our kits to dealer-authorized repair shops). Making the preventative fix simple and effective is better than a long and complicated repair after the failure. Our kits are not usually used for fixing existing damage (only your body shop can determine the correct course of action). But our kits have been proven under extreme conditions on racetracks around the world to prevent many of the costly - and dangerous - chassis problems.
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 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-black anodized aluminum bushing limiters, eight 5mm allen bolts and a drilling template. Our Limiters have a hardcoat anodize (stronger than standard anodizng) and a Teflon coating that prevents the bushing material from bonding with the Limiter.
