PFF5-101G offers an additional +2 of caster and is a high-performance option to PFF5-101 for people wanting the very best from their Mini. This new part, fitted to the rear of the front wishbone has a hard anodised aluminium outer shell with one of our unique low-friction polyurethane centre bushes. The poly/alu combination creates a low friction rotating bush reducing the forces acting on the arm. Lower arm deflection has been decreased by reducing the compliant material within the aluminium shell. Additional caster angle will give more negative camber when cornering giving improved tyre to road contact. Results are greater precision and optimised geometry when turning, improving grip, steering control and feel with less movement in the arm under cornering and braking.
