Powerflex Front Arm Rear Bush Caster Offset – BMW F40 F44 F45 F46 F48 F49 F39 and MINI F54 F55 F56 F57 F60
Upgrade your BMW or MINI suspension with the Powerflex Front Arm Rear Bush Caster Offset, part number PFF5-1302G. This polyurethane front control arm rear bush is engineered for road and fast road use to reduce unwanted suspension flex, improve handling and steering feel, enhance stability, and deliver sharper turn-in. Perfect for drivers who want a performance suspension upgrade that still works brilliantly on UK roads.
Designed to add approximately 1 degree of caster, this offset bush increases in-corner camber gain without compromising straight-line traction. The CNC-machined mount with a knurled body retains grease and allows the bush to rotate freely, preventing torsional twist in the material for improved performance, reliability, and longevity. Expect better tyre contact, more precise tracking, and greater confidence in fast road driving.
Why choose Powerflex PFF5-1302G for your BMW or MINI?
- Road and fast road focused polyurethane bush for durability and control
- Approx. 1 degree caster offset for improved camber control and turn-in
- CNC-machined mount with knurled body for grease retention and free rotation
- Reduces bush deflection for consistent geometry under load
- Prolonged tyre life, improved performance, increased safety, cost-effective upgrade
We use these bushes on our own builds and customer cars, and feedback has been consistently positive: tighter steering, more stable braking, and a noticeable improvement in chassis response compared to tired rubber bushes.
