Powerflex Black Series Rear Lateral Control Arm Inner Bush PFR5-1313BLK for BMW F40 F44 F45 F46 F52 X1 F48 X2 F39 & MINI F54 F

PFR5-1313BLK Black Series Rear Arm Inner Bush Kit

Transform rear-end grip and consistency on your BMW or MINI with this motorsport-grade polyurethane inner bushing kit for the rear lateral links. Built from the Black Series compound, PFR5-1313BLK locks down rear geometry for sharper turn-in, stable toe and camber control under load, and repeatable handling on fast road, track day and competition cars. If you are chasing precision, confidence and durability, this is the chassis upgrade that delivers.

Key performance gains

• Ultra-stiff 95 Shore polyurethane for maximum control in high-load conditions.
• Minimises unwanted movement at the inner pivot of the rear transverse arms to keep alignment true when braking and cornering.
• Consistent feel and longevity compared with ageing factory rubber parts.
• Straight swap for the OE inner mount, no permanent modifications required.
• Perfect for sprint, hill climb, time attack, track day and focused fast-road builds.

We run these bushes on our own builds and customer cars. Feedback is consistently positive, with drivers reporting a more planted rear axle, cleaner feedback through the chassis and confidence-inspiring stability at speed.
