BMW M3 F80 / M4 F82 Ultra Racing Rear Upper Strut Bar
This Powerflex rear differential bracket is specifically designed to reinforce the differential mounting on BMW M2 F87, M3 F80 and M4 F8x models. Manufactured from high-strength aluminium, this bracket uses the second factory mounting point already present on the subframe but not used as standard, allowing for a dual-mount configuration. This setup limits differential movement and rotation under hard acceleration, improving power transfer to the road and drivetrain stability while reducing wheel hop. It also helps reduce the risk of failure encountered on high-power vehicles. This bracket can be used with different bush configurations, although Powerflex ideally recommends using two PFR5-4026 bushes, available in the related products section at the bottom of the page.
