Improve the handling of your E36/E46 in less than an hour! These RTAB reinforcement shims limit rear toe suspension changes of the rear trailing arms.  These shims fill the voids that the factory rubber bushings, increasing the effective stiffness of the bushing without additional NVH (noise vibration harshness).  These shims do not affect ride quality and are perfect for those who are looking for an improvement in handling.

Factory Bushings Don't Last Forever
Whereas the factory rear trailing arm bushings are a common replacement item, few realize that all E36 models (including M3s) use a "light duty" rear trailing arm bushing.  Not until the advent of the 1996-1999 M3 was an improved bushing used, to handle the extra power of the later model E36s.

Even if your car is relatively stock, these bushings are known to dry rot and crack, causing diminished performance.  Getting regular alignments are pointless unless these are inspected regularly, and replaced when necessary.
