OE M3 Rear Trailing Arm Bushings With Limiters

Factory rear trailing arm bushings allow for two undesirable scenarios: premature failure and unexpected changes in toe. Limiting side-to-side deflection of the rear trailing arm, limiters surround the rear trailing arm bushing, maximizing bushing life while eliminating undesired rear toe changes. This alignment retention allows for more predictable handling in corners and over bumps, without a loss of ride quality. Manufactured of wear resistant, noise resistant delrin, ECS RTAB limiters offer a solution to an inferior factory design.
