Rear Differential Lift Kit (Race)

Race Version (Solid mounts, Aluminum Bushings)

+ Take advantage of a 2nd rear diff mount 
+ Raise diff for better axle alignment (via offset bushings) 
+ 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 bracket, rear mounts in subframe, and includes a new rear bracket with two upper mounts instead of the single-mount design used on the original. All mounts are solid aluminum that gives a more direct response with less deflection compared to the factory rubber or urethane mounts. 

The front mounts in this kit are offset 14mm higher than standard mounts. This raises the diff to better align the rear axle shafts with a lowered suspension. As you lower the ride height the angle of the rear axles becomes more extreme, which could cause premature failure in the CV joints. Raising the diff also helps with clearance between the ground and the diff cooling fins. 

The new rear bracket includes a 2nd mount for the passenger side bushing. There is a place for the mount in the rear subframe but BMW chose not to utilize it. These bushings do away with the factory vibration absorber on the upper bolt.
