Powerflex Black Series Rear Axle Carrier Front Mounts for BMW E8x E9x F2x F3x - PFR5-420BLK

Transform the way your BMW steers and puts power down with this race-focused polyurethane mount set from Powerflex. The PFR5-420BLK kit replaces the forward bushes on the rear cradle, locking the rear end in place for cleaner geometry control, crisper response and rock-solid stability on fast road and circuit. Built from a high-durometer 95A compound, these performance mounts outlast and outperform ageing OE rubber and keep your alignment consistent under braking, cornering and hard acceleration.

Ideal for drivers chasing precision and repeatability, this direct-replacement pair dramatically reduces cradle deflection and rear-end float. Expect tighter rear axle location, more confident turn-in and improved traction off the apex. We run these on our own builds and have installed them for countless BMW owners; feedback is consistently strong on feel, feedback and durability.

Why this upgrade stands out

• Motorsport-grade polyurethane for maximum control and consistency
• Minimises rear cradle movement for stable handling and grip you can trust
• Helps reduce axle tramp and improves power delivery on corner exit
• Maintains suspension geometry under load for repeatable lap-after-lap performance
• Resistant to oil, road salt and heat for long service life
• Direct replacement design for a secure, accurate fit
