Since the M3 is down for this race season as I continue to change my preparation plan, I'm looking to sell my fresh built differential. It has a BMW Motorsport 4.75 gear set purchased new from BMW. This was built by Brett Anderson (Koala Motorsports) so it's a top notch build. Features 30/90 ramps, 4 clutch, REM polished. Never been run, brand new. Does not include an E30 rear cover (has some other generic cover for protection). No core required, would consider partial trade. $4400 plus shipping from 48375.

Cheers.
