BMW F80 M3 Street Performance Dual Mount Differential Bushing Reinforcement Kit – Enhanced Stability, OEM+ Comfort & Improved Handling Precision | Fits 2015–2018 (S55 Engine)

Bring balance to performance and comfort with the BAVMODS® Dual Mount Differential Bushing Kit (Street Performance Edition) — a precision-engineered solution that strengthens your rear differential mounting system while preserving the refined feel of daily driving.

Designed for BMW enthusiasts who want improved drivetrain response without introducing harsh noise or vibration, this system replaces the factory soft rubber mounts with reinforced performance-grade rubber bushings that offer greater rigidity and durability while still absorbing road vibration.

The kit also converts your factory single front differential mount into a dual-mount system, adding a second anchor point to the subframe for increased stability under acceleration. The result is smoother power delivery, tighter traction, and improved throttle response — all without compromising everyday comfort.
