Powerflex PFF5-6001G Front Radius/Thrust Arm to Chassis Caster Offset Polyurethane Bush Kit for BMW 6 Series F06 F12 F13 (Gran Coupe, Convertible, Coupe) - Set of 2, Diagram 1 | OEM 31126775971/31126775972

PFF5-6001G Caster-Increasing Polyurethane Bushings - Front Tension Strut to Body - BMW F06 F12 F13 6 Series

Transform front-end precision and confidence with this PFF5-6001G caster offset polyurethane bushing kit. Designed for the BMW 6 Series F06 Gran Coupe, F12 Convertible and F13 Coupe, these performance bushes replace the soft factory rubber in the front lower arm rear position, often called the tension strut, thrust arm or front control arm rear bush. Expect tighter steering, better stability under braking and a more planted feel in fast bends.

The engineered 6 mm offset delivers approximately +/- 0.5 degree additional caster. More positive caster increases dynamic negative camber on turn-in, keeping the tyre contact patch flatter on the road, boosting front-end grip and response without sacrificing day-to-day comfort.
