Our PFF76-902G Front Wishbone Rear Bushings have been designed around our unique, on-car adjustable, Nylon/Polyurethane Ball-Joint combination for more direct steering input and improved cornering and braking ability. The offset bore allows for +/- 0.5-1.0 of caster adjustment with the supplied spanner wrench to assist the fine-tuning of the side-to-side caster settings. Vertical stiffness is increased by 250% over standard rubber.
