E46 M3 Finned Differential Cover by Motorsport 24!

M24 addresses the E46 M3’s weak differential cover by building a one-off cover machined completely from billet aluminum stock. The flexible OE bushings are eliminated for a simpler, more robust design that also more immediately transfers power through the drive train and to the rear wheels. Cooling fins are integrated into the cover, while the cover’s extra reinforcement ribs increase the strength of the mounting flange. The mounting ears on the differential cover are also reinforced, which addresses a known failure point of the original E46 M3 differential cover.
