ECS Tuning Complete Polyurethane Differential Bushing Set 95A for BMW M2, M3, M4
Upgrade your BMW M2, M3, M4 differential mounts with the ECS Tuning 95A polyurethane bushing kit. This complete poly differential bushing set replaces soft, worn factory rubber bushings to tighten the rear end, reduce wheel hop, improve throttle response and deliver sharper power transfer to the wheels. Ideal for fast road, track day, drag racing and drift use while remaining streetable, this 95A durometer kit is engineered to handle extreme driveline forces without the harshness of solid or Delrin mounts.
Why upgrade the OEM rubber differential bushings
- Factory rubber diff bushings are a wear item and commonly crack or degrade on F8X platform cars, leading to slop and vibration.
- Unwanted driveline movement causes wheel hop, delayed throttle response and inconsistent traction.
- Polyurethane bushings control deflection for a more connected, precise driving feel.
What you get
- Complete set of ECS Tuning performance polyurethane differential bushings and associated subframe mounts for the rear differential assembly.
- 95A durometer red polyurethane isolators that reduce drivetrain movement yet keep NVH at a sensible street level.
- Black Type II anodised 6061 T6 aluminium sleeves and CNC billet inserts for superior durability and corrosion resistance.
Real results you can feel
- Reduced driveline deflection for crisper throttle response.
- Significant reduction in wheel hop for better traction and control.
- Improved power delivery when cornering, accelerating and on uneven surfaces.
- More precise rear end stability without the harsh vibration of solid mounts.
Engineering that lasts
- Poly formulation, profile and loaded surface area are designed to minimise stress concentrations and stay within acceptable compressive strain limits.
- Engineered to withstand high torque loads and worst case driveline conditions.
- Resistant to chemicals, ozone degradation, road salt and general wear for a longer service life than rubber bushings.
Fitment
BMW M2, M3, M4 including F87 M2, F80 M3, F82 and F83 M4 on the F8X platform. Ideal as an upgrade or replacement for cracked, worn or soft OEM differential bushings and subframe mounts.
