Powerflex Black Series PFR5-422BLK Rear Subframe/Axle Carrier/Cradle-Crossmember Mount Bushes/Bushings (Pair) - BMW 1 2 3 4 Series E8x E9x F

Powerflex Black Series Rear Axle Carrier Rear Mounts - PFR5-422BLK - BMW 1 2 3 4 Series

Transform rear-end stability and cornering confidence with this race-focused polyurethane rear axle carrier rear mount set. Powerflex Black Series, part number PFR5-422BLK, uses a 95 Shore A compound to control movement of the rear cradle, locking in alignment and delivering crisp, predictable handling on track and fast road builds.

If you want the rear of your BMW to stay planted under acceleration, braking and rapid direction changes, these performance bushes are the upgrade. We run them on our own cars and our customers consistently praise the sharper response, improved traction out of bends and the durable, fit-and-forget design.

Main advantages

• Stiff 95A Black Series polyurethane keeps the axle carrier located for precise geometry control.
• Reduces subframe shift under load to maximise tyre contact and mechanical grip.
• Firmer, more connected feel from the rear chassis without the maintenance of solid mounts.
• Consistent performance lap after lap thanks to heat, oil and abrasion resistant material.
• Superb upgrade for track days, time attack, drift and spirited road use.

Why enthusiasts choose this upgrade

• Holds alignment under heavy loads to reduce unwanted rear steer.
• Enhances stability during hard launches and high-speed sweepers.
• Outlasts ageing rubber mounts that soften, crack and allow excess cradle movement.
• Ideal companion to coilovers, uprated anti-roll bars and performance tyres.

Note: Expect a modest increase in cabin feedback compared with tired OE rubber, which is typical of competition-grade polyurethane.
