Engine movement (deflection) is wasted horsepower, and that power is yours BMR Suspension wants you to take it back with its polyurethane motor mounts for 2016 and newer Chevrolet Camaro. BMRs new motor mounts (MM009) are far superior to the bulky, stock bushings, which are designed for comfort, not performance. BMR manufactures its MM009 polyurethane motor mounts in its Florida facility from CNC - machined billet aluminum with 95 - durometer polyurethane bushings. The kit is completed with Grade 8 hardware.
