Fall Line’s monoball spherical bearing conversion kit transforms the front steering and suspension feel of the M3/M4. The factory rubber bushing is very large and is prone to substantial deflection under load as the car is put through its paces. Deflection of the bushing can create unwanted geometry change, steering wobble under braking, and even hysteresis of the thrust arm.

The bearing’s housing is precision machined from aluminum, creating a rigid part that allows the M3/M4’s thrust arm to move smoothly through its range of suspension travel. The improvement in steering and suspension feel is immediate and truly enhances the personality of the new G8x.
