BMR Performance Decrease wheel hop and increase the rear stability of your 2015-2019 S550 with BMR's differential bushing kit! The 2015-2019 Mustang differential sits inside the IRS system and has four bushings holding it in place. These bushings are very weak and have too much movement in them that causes deflection. BMR includes 95 durometer polyurethane bushings to decrease deflection which reduces wheel hop and any other unwanted movement. This kit is designed for street, drag race, and road course applications and can be installed in 3-4 hours.
Heavy Duty Hardware This kit now includes heavy duty hardware for owners that plan on launching their Mustang hard at the track. BMR's new hardware prevents differential mounting bolt failures with higher than stock power levels, or hard launches. Hardware upgrade requires slight modification to the rear differential mount.
