VAC Motorsports Aluminum Differential Mount Kit, BMW E46 M3

Our VAC Solid Differential Mount Kit is designed to unitize the differential housing and the chassis.

By mounting the diff using solid mounts, you eliminate all torquing and twisting of the diff-housing within the subframe; this results in improved driver feedback, improved lap times, and better reliability eliminating many troublesome front mount-bolt and mounting tab failures. Our solid mount kit is ideal for track, race, and extreme performance street vehicles with high grip tires.

VAC Tech Tip:
Despite their solid construction, we have customers that use these in their street driven E46's. Keep in mind, ride quality is not significantly compromised, however significant additional gear noise will be transmitted to the cabin in trade off for more strength.
