KIES MOTORSPORTS, LLC — TERMS AND CONDITIONS OF PURCHASE AND SALE

Revshift polyurethane differential bushings completely replace the oem rubber bushings on the BMW F80 / F82 / F83 / F87 - M4 / M3 / M2. This kit includes a second rear bushing and dual mount bracket that adds a mounting point to the subframe. These bushings securely mount the differential eliminating wheel hop and improving the vehicles handling capabilities. The two piece bushing design sandwiches the subframe locking everything in place. The bushings will not shift while driving like other one piece designs allow. The dual mount bracket was carefully designed for strength and a precise fit. This kit is entirely made at Revshift in the USA from our proprietary polyurethane formula and CNC machined 6061-T6 billet aluminum.
