Powerflex PFF5-6004G Camber Adjustable Front Upper Wishbone/Control Arm Bush for BMW F07, F10 F11 xDrive, F06 F12 F13 xDrive, F01, i8 & Rolls-Royce Ghost - Polyurethane +/-0.5 deg

Front Upper Arm Camber-Correcting Poly Bush Kit for BMW F-Series xDrive, i8 and Rolls-Royce Ghost

Part number: PFF5-6004G

Transform front-end feel and alignment control with this camber-adjustable polyurethane upper arm bush kit. Designed for selected BMW F-Series platforms and the Rolls-Royce Ghost RR4, these precision-engineered bushes replace the soft factory rubber to give crisper steering, more stable geometry under load and the ability to dial in extra negative camber for fast-road use.

The uprated polyurethane construction is approximately 66 percent firmer than the OE bush, cutting compliance that leads to vague steering and uneven tyre wear. On-car adjustment of plus or minus 0.5 degree per side makes it easy to fine-tune front camber for better turn-in, improved grip and smarter tyre life without compromising daily usability.

This is a Road Series upgrade, so it is a genuine performance handling improvement while remaining suitable for everyday driving. At MJ Modifications we have fitted this kit for customers and on our own builds, and the feedback is consistently positive on steering precision, camber stability and alignment retention.
