Rear chassis crossmember specifically designed to work with our modified rear subframe for E21.
This custom rear crossmember is welded over the existing one and allows the use of a 'twin-ear' E36 diff cover on your medium case diff. This provides more stability than the single support cover and is recommended for cars with high hp engines such as turbocharged M20's.
Installation of this part requires welding and the removal of the existing diff hanger on the car. Two bolts allow for a rear strut brace to be connected to this crossmember. Two extra pieces of sheet metal are supplied to be welded on either side and make the connection to the wheel wells for extra rigidity.
