Powerflex Black Series Adjustable Camber Front Lower Control Arm/Wishbone Front Mount Bush Kit - BMW 1 Series F40/F52, 2 Series F44; MINI F54/F55/F56/F57/F60 - Polybush Suspension Upgrade PFF5-1301GBLK

Powerflex Black Series Adjustable Camber Front Lower Wishbone Front Mount - PFF5-1301GBLK

Sharpen your front axle and unlock confident turn in with this motorsport-grade polyurethane front wishbone front mount set. Designed for BMW 1 Series F40 and F52, BMW 2 Series F44 Gran Coupe, plus MINI F54, F55, F56, F57 and F60, this upgrade delivers crisper steering feel, better on-centre stability and more even tyre wear thanks to precise camber adjustment and reduced compliance.

The Black Series compound is a stiff 95 Shore A polyurethane engineered to control arm movement under heavy braking and cornering, keeping geometry consistent for fast road, track day and competition use. If you want a tighter front end and repeatable alignment settings that last, this is the bush kit to choose.

At MJ Modifications we have installed these on customer builds and our own development cars with excellent results. Feedback is consistently positive on steering accuracy, stability at speed and durability compared to tired rubber mounts.

Key advantages

• Adjustable camber at the front lower arm to optimise contact patch and reduce shoulder wear
• High-stiffness 95A polyurethane to curb unwanted arm deflection under load
