Suspension mounts are designed to absorb the energy of the shocks and springs and isolate road harshness from the chassis. But over time the original rubber mounts will crumble and fail. We have stock mounts and bushings as well as a wide selection of upgraded and heavier-duty for performance street cars. We also offer a full selection of race only bushings and mounts. Simply choose your car below. Included here you will find rear shock tower mounts, front strut mounts, subframe mounts, lower control arm bushings, rear trailing arm bushings, and more.
Lower half of the bushing is Purple 80A durometer, while the upper half is Yellow 70A. This rear position subframe bushing is specifically for the E46 M3!
Chassis consistency is the foundation of predictable lap times. The semi-trailing arm rear suspension geometry utilized in the BMW E36 318ti and Z3 platform is highly sensitive to dynamic alignment changes under load.

In professional motorsport, chassis predictability and geometric stability are non-negotiable. Standard factory rubber bushings are designed for low-frequency compliance, but under dynamic loading, they suffer from significant deflection. This deflection distorts your suspension geometry, slows down anti-roll bar transition times, and masks critical feedback from the rear axle.

Factory-issued rubber sway bar bushings are engineered for commuter comfort, meaning they are prone to significant deflection under lateral loads. Over time, environmental exposure and hard cornering cycles cause these rubber units to soften, stretch, and perish, leading to unpredicted handling characteristics, delayed steering response, and vagueness at the limit.
