Rear Upper Inner Spring Arm Bearings, Ground Control - E36, E46, E83, E85, E89

Solid bearings replace BMW part numbers 33321092247 and 33321137571 for all E36 (except Ti), E46, E85 Z4, and E89 Z4.

When tuning a suspension, the movement of the entire chassis and suspension components must be taken into account. For the track we prefer to have a solid bushing that does not allow any deflection away from our intended alignment but also allows the suspension to run smoothly through its intended arc. Installing solid spherical suspension mounts completely eliminates unwanted flex, allowing far more precise suspension tuning and faster lap times.

These control arm bearings replace the stock rubber lateral control arm bushings. Inner bearings are aircraft quality spherical bearings in an anodized machined housing. Check your rulebook but these should be legal in SCCA IT, BMW CR Modified, and other racing classes. Recommended only for track use, not street use.

Priced per pair.
