Powerflex Poly Bushes Pack Track Front Radius Arm To Chassis Bushes - E82 1 Series M Coupe (2010-2012) - PFF5-401GBLK

BMW E82 1 Series M Coupe Front Radius Arm to Body Poly Bush Kit

Part number: PFF5-401GBLK

Transform turn in, sharpen steering feel and stabilise braking with this motorsport-grade polyurethane bush kit for the BMW E82 1 Series M Coupe, 2010 to 2012. Built for enthusiastic driving and circuit work, this upgrade replaces the soft factory items with a precision engineered solution that resists deflection, keeps alignment true and delivers confidence on fast road and track days.

We run this setup on customer cars and in our own builds. Feedback has been superb, with drivers reporting crisper response, better mid-corner support and rock-solid stability under hard braking.

Why enthusiasts choose this upgrade

• Motorsport-ready compound, Black 95 Shore A, for maximum control of suspension geometry
• Stainless steel offset sleeve provides on-car caster adjustment of up to plus or minus 0.75 degrees
• Steel outer shells spread load for durability during heavy track use
• Reduces arm movement compared to tired factory rubber by a massive margin for consistent handling
• 25 percent stiffer than the previous version and around 140 percent firmer than worn OE bushes
• Includes adjustment spanner for quick setup changes

What this means on the road and track

• More camber gain as you load the front axle for increased front-end bite
• Improved straight-line stability at speed
• Cleaner feedback through the wheel and reduced shimmy under hard braking
• Holds alignment under load for repeatable lap-after-lap consistency
