Product Details

10X Entries For Our 25th Anniversary Sweepstakes!
Only for use with Poly Diff Bushings!

All F8X M2/M3/M4s make great power right off the assembly line, and 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 hydraulic (fluid filled) and even street-driven cars are known to fail in as little as 30,000 miles.

With the Turner Motorsport Dual-Mount Differential Plate, we capitalize on this second bushing location, prolonging bushing life and more positively affixing the differential, resulting in the tendency for wheel hop and providing crisper driveline response.""

This Kit includes the addition of an ECS Poly Rear Position Diff Bushing, to use with the Turner Dual Mount plate.

Features & Benefits:

  • Allows for the addition of a second rear-position differential bushing
  • ​This Kit Includes 1 ECS Poly rear-position differential bushing
  • Helps reduce unwanted drivetrain deflection; offers a more enhanced driving experience by removing unwanted movement
  • Engineered by Turner to withstand extreme driveline forces
  • Manufactured from 6061-T6 billet aluminum, type II anodized for corrosion resistance
  • Fully reversible, bolt-on installation; hardware included.
  • Polyurethane bushings are needed for this kit
