Powerflex Black Series Rear Differential Rear Mounting Bushes (Pair) PFR5-6031BLK for BMW F01 F02 F03 F04 F07 5 & 7 Series, Rolls-Royce Ghost Wraith Dawn RR4 RR5 RR6

Powerflex Black Series Polyurethane Rear Final Drive Mount Bushings, Part Number PFR5-6031BLK

Transform rear-end stability and driveline control with this motorsport-grade polyurethane mount kit. The Powerflex Black Series bushings use a 95 Shore A compound designed for serious performance driving, giving a much firmer, more precise feel than tired factory rubber. Expect crisper throttle response, reduced differential movement, improved traction on corner exit and more consistent handling when pushing on.

We have installed these at MJ Modifications and feedback from owners has been excellent. Drivers report a tighter rear axle, less shunt under load and noticeably cleaner power delivery. If you want a confident, planted rear end for fast road, track day or competition use, this upgrade delivers.

Why this upgrade

• Black Series 95A polyurethane for maximum control of rear driveline geometry
• Minimises diff movement for sharper launches and reduced wheel hop and axle tramp
• Holds alignment under load for repeatable handling and predictable grip
• Direct-fit replacement for worn OE rubber mounts
• Built for durability and consistent performance in demanding conditions
