Sharpen your G87 M2 driveline response with Powerflex PFR5-4026

Looking to control rear-end movement and put power down cleanly on your BMW G87 M2? The Powerflex PFR5-4026 rear final drive mount is a proven upgrade that tightens up the differential support, helping to cut axle tramp, tame wheel hop and improve traction during hard launches and spirited driving. It is a direct-fit replacement that delivers a stronger, more precise feel from the back of the car, ideal for fast road, track day and drag strip use.

Built with Powerflex’s renowned purple polyurethane in an 80A shore hardness and paired with a black anodised aluminium insert, this bush provides robust location of the rear differential without the rapid wear associated with factory rubber. A built-in support washer adds extra reinforcement under heavy load for consistent performance and long-term durability.

Why enthusiasts choose it

• Crisper throttle pick-up and more consistent launches
• Reduced driveline wind-up and improved stability under acceleration
• Helps limit differential movement to keep the rear end planted
• Durable material resists oil, heat and ageing far better than OE rubber
• Direct replacement design for straightforward installation

Works with optional twin-mount bracket

Want even more support for high-power builds? PFR5-4026 can be used with the Powerflex PFR5-4030 dual-mount rear differential bracket, allowing you to install two bushes in the standard locations for extra reinforcement.
