BMW Fall-Line Motorsports G8x / F8x M2 / M3 / M4 Rear Upper Control Arm Bearing Set

MADE IN THE USA. Rubber bushings found in the G8X’s rear upper arms are the last weak link in an otherwise rigid suspension. The original BMW bushings yield to cornering forces applied to the suspension, resulting in camber and toe change that is not ideal for performance driving. Fall Line’s kit replaces the soft upper control arm bushings with spherical bearings, enabling the rear suspension arms to move smoothly through their travel and giving the rear of a car a more solid, planted feel. The reduced geometry change allows for the car to retain its desired alignment, maintaining better control over the tire’s behavior under heavy load. Designed to replace the inner bushings of the rear upper control arms; BMW Part Numbers: 33322284777, 33329504611, and 33329504612.
