Fits: All E30 Non-M, E30 M3.

Benefits:
-Stiffens the rear end feel (driver feedback)
-Increases driveline stiffness (control)
Note: Solid mounting the differential will increase NVH. 

Material: 
6061-T6 Aluminium - Anodised Purple

These bushes make the back end feel tight and responsive improving the control and feedback to the driver for a superior driver feedback and stability.

As the diff on an E30 chassis is a stressed member and hard mounted to the subframe, solid mounting the diff is considered a must if you intend to solid mounts the rear subframe to the chassis.
We consider it wise to solid mount the diff when using aluminium subframe bushings otherwise the downward deformation of a flexible bush can result in bending on the mounting studs.
