BimmerWorld Solid Aluminum Differential Mount Set - F22, F30, F32

F22, F30, F32 solid aluminum mounts for the differential.

Solid diff mounts are a great upgrade over the factory rubber, especially for dedicated track and race use.

+ Upgrade your existing urethane or rubber dual-mount rear bracket to solid
+ Solid bushings have near-zero flex or axle wind-up 
+ More power transferred to the wheels 
+ More direct and positive feedback and road feel 
+ Eliminate the potential failure of stock bushings

This bushing set covers the front and rear mounts in the subframe. On race cars we prefer aluminum to minimize deflection as much as possible. Even most urethane products are still geared for street use. While urethane might be fine for street use they pale in comparison to solid when used on the track. Solid materials have almost zero wear and tear, eliminating another maintenance item from your prep list.

Because of the solid nature of these bushings we only recommend them for track use. We do offer several urethane options if you want a more street-friendly bushing option.

Hardware can be re-used from the original mounts except for the ellipsoid self-locking nut for the rear mount. BMW recommends replacing this nut, part #33306760349. See our Related Items below for the nut or a hardware replacement kit.
