New from BMR Suspension – the 1978-87 GM G-Body Coil-Over Conversion Kit. This kit increases traction and adds ride height adjustability while being easy to install. See more details below.

Official Release:

Increase traction and add ride height adjustability to the rear of your 1978-1987 GM G-Body with a Coil-Over Conversion Kit from BMR Suspension. OE-style lowering springs can drop the vehicle, but do so at the expense of suspension and shock travel. By utilizing a conventional coil-over, the vehicle can ride at a lower ride height, while still retaining full suspension travel. BMR manufactures its Coil-Over Conversion Kits from CNC-laser cut, CNC-formed 1/4-inch steel plate for strength, lightweight, and, precise fitment. These also give you three mounting positions for the lower control arm. This allows for easy instant center and anti squat changes, so you can fine-tune the car’s rear suspension geometry. Whether you want to aggressively lower your Mustang or you want the added suspension control you get with coil-overs, BMR makes it easy to add coil-overs to the rear of your car.

Designed for street performance, drag race, and handling applications, BMR makes its coil-over brackets from strong 1/4-inch laser-cut steel plate plate. These plates simply bolt in place and allow for commonly available coil-over shocks to bolt in. This kit is designed to work with any coil-over with a 1.25-inch wide bushing and ½-inch bolthole. When performance is a must, rely on BMR Suspension!

***BMR designed the CCK007 with Viking Performance coilover shocks. BMR recommends Viking part number C207W or C217W shocks. The C207W shocks require 10-inch springs. The C217W shocks require 10-inch springs. BMR recommends 175lb springs for both length shocks.***
