Powerflex Front Wishbone Rear Bush with Adjusted Caster

---

This is a variation of Powerflex’s popular Front Wishbone Rear Bush with the addition of +2 degree of caster bushes built in. The caster provided in this bush is not adjustable it is a fixed +2 degrees. The front wishbone bushes on a standard MINI are rubber and prone to perishing and becoming soft over time which increases play in the chassis. Powerflex polyurethane bushes resist corrosion and softening far better helping to improve handling. Additional caster angle will give more negative camber when cornering giving improved tyre to road contact. Results are improved geometry when turning giving additional grip, steering control and feel with less movement in the arm under cornering and braking. Powerflex Front Wishbone rear bush for is suitable for the MINI One, Cooper, Cooper S, JCW and GP and adds +2° of caster. The front wishbone rear bush is fitted to the rear of the front wishbone has a hard anodised aluminium outer shell with one of Powerflex's unique low friction polyurethane centre bushes. The polyurethane and aluminium combination creates a low friction rotating bush reducing the forces acting on the arm. Reducing the compliant material within the aluminium shell has decreased lower arm deflection. When fitting this Powerflex bush to your MINI we suggest fitting a Powerflex Front Wishbone inner ball joint with camber adjustment, which offers additional negative camber, we recommend using PFF5-101G which neutralises the caster lost by moving the arm position bringing the caster angle back to standard.
