Here I am offering a brand new set of the ORIGINAL E46 M3 rear trailing arm bushing / RTAB shim kit - and still the best! As Used on my own personal E46 M3 Coupe. Also compatible with E36 M3, Z4 and X3. Made in the USA, the Turner rear trailing-arm bushing limiter kit creates a stiffer rear suspension without sacrificing ride quality. Stock trailing arm bushings are known for early failure, on both the E36, Z4 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" poly bushings. All the while maintaining completely silent operation - no squeaks and no vibration, whatsoever. Poly bushes are great on track, but ultimately compromise the ride on UK roads. By using the Turner motorsports bush limiter kit with BMW OE RTAB bushes, you get to improve performance, feel and longevity without sacrificing ride quality. They really are the best of both worlds. You get to have your cake and eat it! By combining these limiters with stock OE BME RTAB 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, owners 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: 4x black anodized aluminum bushing limiters, eight 5mm allen bolts and a drilling template. This covers left and right sides. The Turner Limiters have a hard-coat anodise (stronger than standard anodising) and a Teflon coating that prevents the bushing material from bonding with the Limiter. Unlike other shims/bush limiters; the Turner ones are held in place with the supplied Allen bolts. This stops the limiter rotating and therefore causing noise.These are silent when fitted. In stock ready to dispatch. Please let me know if you have any questions. Your Price for the limiter kit is only £125 Delivered. While stocks last.
