The BMR Coil-Over Conversion Kit converts the rear suspension of 1964–1972 GM A-Body cars to accept conventional coil-over shocks, adding traction and ride-height adjustability while retaining full suspension travel. Built from CNC laser-cut 1/4-inch steel plate, the bolt-on brackets give five lower-control-arm mounting positions for instant-center and anti-squat tuning. They accept common coil-overs with 1.25-inch bushings, install in about 2–3 hours and finish in black hammertone.
