Powerflex PFR5-4615G Rear Alignment Arm and Bush Set for BMW E36, E46, M3, Z4, X3

Dial in proper rear geometry and cure inner shoulder tyre wear with the Powerflex PFR5-4615G rear suspension solution. This Road Series arm and bushing combo lets you fine tune rear wheel angle on-car for sharper turn-in, stronger traction out of bends and a more stable, confidence-inspiring BMW on British roads and fast road use. Perfect if your car is lowered or running wider wheels and needs precise rear alignment to get the most from your chassis.

We run this on our own builds and customer cars. Feedback is consistently positive with crisper rear-end response, better contact patch control and no harshness associated with metal joint conversions. It is a fit-and-forget upgrade for daily driving, spirited B-roads and occasional circuit use.

Key advantages

• On-car adjustment range approximately +1.0 degrees to -3.0 degrees for accurate rear wheel angle correction on popular BMW platforms
• Performance-grade polymer bushings deliver OE-like refinement with improved durability over rubber
• Sharper handling, improved stability under load and more predictable balance in wet and dry
• Reduce inner-edge scrub and extend tyre life on lowered or hard-driven vehicles
