The Bimmerworld E46 M3 Solid Aluminum Differential Bushings completely eliminate movement under acceleration. Solid diff bushings essentially take out any slop, allowing your suspension to work more efficiently and allowing you to put power to the ground more quickly and effectively. A great addition to your Diffsonline Race Differential for your E46 M3.
Kit replaces all three mounting points with aluminum bushings.
Note: Recommended for dedicated track cars, race cars (where class rules allow) and street cars with high power output. Will likely increase NVH.
