M2/M3/M4s make big power right off the assembly line, & are frequently driven hard. Massive horsepower cars are not unusual. All of this wouldn't present a problem - except - BMW built provisions for dual rear differential bushings, however only utilized one! Early cars are especially failure-prone, with differential bushings being fluid filled & even street-driven cars are known to fail in as little as 30,000 miles.


We capitalize on this second bushing location, prolonging bushing life & providing crisper driveline response.
