Competition Engineering designed these Progressive Rate C2575 Rear Coilover Springs to reduce the rate of compression, making it less likely to "drive up" on the tire during violent wheel stands. As the vehicle pitch rotates the weight to the rear wheels, this compresses the spring making it more conducive to lifting the front end. Progressive springs compensate for added rear weight in Street Rods and Pro Street cars using a back seat. Competition Engineering powder coats these coilover springs to provide an attractive finish and helps extend spring life.
