Powerflex Black Series Front Upper Wishbone/Control Arm Bush PFF5-6004BLK for BMW 5/6/7 Series F10 F11 F06 F12 F13 F01, i8 & Rolls-Royce Ghost (Polyurethane, Set of 4)

PFF5-6004BLK Front Upper Arm Bush Kit for BMW F-Series and Rolls-Royce Ghost

Transform front-end precision with this motorsport-grade upper arm bush set, part number PFF5-6004BLK. Built from a 95A hardness polyurethane compound, this kit keeps the front geometry locked down under braking and cornering, delivering razor-sharp response and consistent handling on fast road, circuit and time attack use.

At MJ Modifications we fit these on our own builds and customer cars. Feedback has been excellent, with noticeably crisper turn-in, better mid-corner stability and alignment that stays true even under heavy load.

Key benefits

• High-durometer poly bush material for maximum control of the front upper link
• Minimises compliance in the top arm pivot to sharpen steering feel and braking stability
• Direct replacement for ageing OE rubber inserts that soften and split over time
• Durable and consistent performance for track days, sprint, hillclimb and fast road
• Helps maintain camber and caster targets for repeatable alignment

Note: Performance compound may increase NVH compared with factory rubber. Chosen by drivers prioritising precision and feedback.

What you receive

• 4 x front upper arm bushes

One car requires four pieces.
