RK-Tunes Differential Brace F80 | F82 | F83 | F87 | M2 | M3 | M4

This is the key to fixing wheel hop / limit diff travel!

It simply replaces the existing single-bushing bracket bolted to the rear of the differential with a new billet aluminum bracket designed to add a second bushing 

Note* The single bushing option is suggested if you have aftermarket polyurethane bushings already or just want to add one bushings. We suggest a full set of bushings if you have oem diff bushings. Powerflex bushings are the best we have used and it is what we included.

new hardware is included also
