Powerflex Black Series Front Arm Rear Bush - Caster Offset - BMW 1 Series F40, 2 Series F44, F52 Sedan, MINI F54 F55 F56 F57 F60
Part number: PFF5-1302GBLK
Unlock sharper turn-in, improved camber control and rock-solid stability with the Powerflex Black Series Front Arm Rear Bush Caster Offset for BMW and MINI. This track-focussed polyurethane bush is engineered to deliver approximately 1 degree of caster offset, enhancing in-corner camber gain without compromising straight-line traction. Built around a CNC-machined mount with a knurled body to retain grease and allow free rotation, it minimises torsional twist, boosts reliability and increases longevity for consistent performance on road and track.
We run these bushes on our own cars and customer builds and the feedback is consistently positive: crisper steering response, more confident braking, better stability at speed and repeatable performance during hard driving and track days. If you want a no-compromise BMW MINI suspension upgrade that tightens up the front end and keeps geometry in check, this is the proven solution.
Why choose Powerflex Black Series
- 95 Shore A Black Series compound for maximum control of chassis geometry on track, race and rally.
- Caster offset design for enhanced camber gain and sharper turn-in.
- Knurled, grease-retaining body allows free rotation of the bush to prevent torsional wind-up and reduce wear.
- CNC-machined mount for precision fit and repeatable performance.
- Ideal for fast road, track day and motorsport use.
