Powerflex Poly Bushes Pack Track Front Radius Arm To Chassis Bushes - E90, E91, E92 & E93 3 Series (2005-2013) - PFF5-401GBLK

Part number: PFF5-401GBLK

Unlock razor sharp steering, rock solid stability under braking and consistent alignment with this Black Series caster adjustable front lower arm rear mount for BMW E90, E91, E92 and E93. Built from ultra firm 95A polyurethane with steel outer shells and a CNC machined stainless offset sleeve, this uprated tension strut to body bushing is the no compromise suspension upgrade for trackdays and serious fast road use.

On-car adjustability gives up to +/- 0.75 degrees of caster correction, delivering extra in-corner camber gain, crisper turn-in and greater straight line confidence. The latest design is around 25 percent stiffer than the previous version and approximately 140 percent stiffer than tired factory rubber, dramatically reducing deflection and keeping the front geometry locked in when you lean on the brakes and load the front axle through high speed corners.

• Black Series 95A polyurethane for maximum control of suspension geometry
• Steel outer shells for superior load distribution and durability
• CNC stainless offset sleeve with supplied spanner for precise on-car caster adjustment
• Improved braking stability and steering precision on track and fast road
• Direct replacement for the front lower control arm rear mount on E9x platforms

We run these ourselves and our customers love the transformation. Expect cleaner feedback through the wheel, better mid-corner grip and alignment that stays true lap after lap.
