BMW F82/F83 M4 Track Performance Dual Mount Differential Bushing Reinforcement Kit – Enhanced Stability, OEM+ Comfort & Improved Handling Precision | Fits 2015–2018 (S55 Engine)

Unleash the full potential of your BMW’s drivetrain with the BAVMODS® Dual Mount Differential Bushing Kit (Track Spec) — a complete billet aluminum conversion system designed to eliminate flex, stabilize the rear differential, and deliver uncompromising performance under extreme conditions.

From high-torque street builds to full track-spec M cars, the factory rubber bushings and single front differential mount simply can’t handle the stress. Under load, these soft bushings allow the differential to twist and shift — causing drivetrain lash, wheel hop, and power loss.

This upgraded dual-mount system completely eliminates those weak points by converting your single front bushing setup into a dual billet-mounted configuration. Precision CNC-machined solid metal bushings ensure a direct, rigid connection between the differential and subframe, providing unmatched strength, feedback, and consistency — even during hard launches or aggressive corner exits.

Key Features & Benefits

• Dual-Mount Conversion: Converts factory single-mount design to a true dual-mount setup for maximum stability.
• Solid Metal Bushings: Zero deflection under load — completely eliminates drivetrain flex and bushing movement.
• Instant Power Transfer: Delivers direct torque response and eliminates the “rubber delay” felt in OEM setups.
• Eliminates Wheel Hop: Prevents rear-end oscillation and keeps traction consistent during acceleration.
• 6061-T6 Billet Construction: CNC-machined bracket and bushings provide race-grade durability and precision fitment.
• Enhanced Cornering Stability: Keeps the differential locked in place, maintaining perfect geometry under lateral load.
• Track-Tested Design: Built for high-power builds and demanding circuit conditions.

*Intended Use

This is a Track Spec upgrade intended for high-performance and competition applications.

While installation is 100% bolt-on, NVH (Noise, Vibration, Harshness) will increase compared to OEM or polyurethane systems due to the rigid, all-metal construction.

Ideal for drivers who demand total drivetrain control and precision feedback.
