BMW Suspension Bushings & Mounts

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.

Any subframe work or reinforcement project on the rear of the E46 M3 should include a new set of subframe mounts. It's the worn rubber bushings that contribute to failed rear subframes on the E46 (but not the only reason). As the rubber gets worn, there is more flex to the mount. This flexing is then transferred to the sheetmetal in the floor where the spot welds will pop and the sheetmetal will crack. Additional force coming from stiffer suspensions and stickier tires will only increase the flexing of the mounts/chassis.

Of course, stiffer mounts would help prevent this problem but with a stiffer bushing comes ride harshness, vibration, and additional noise. Our engineers and technicians recommend replacement with the factory rubber bushings (along with the appropriate reinforcement of the floor). The rubber bushings help isolate bumps and impacts and are quiet. They are also a perfect fitment and require no maintenance.
