Designed for street performance, drag race, and handling applications, BMR makes its coil-over brackets from heavy-duty ¼-inch laser-cut steel plate. These plates tie in to the frame and upper A-arm mount, which strengthens the mount as well. BMR also provides a drill guide that allows you to cut the shock opening in the frame with a simple hole saw and drill, rather than requiring a torch or plasma cutter. This kit can be installed with the motor in the car and the fenders bolted on. When performance is a must, rely on BMR Suspension!
