Constructed of 6061 CNC Machined aluminum sleeves and SAE 9254 Cold Wound Steel coil springs, the coil-over system is designed for competition as well as high-performance street use. The higher spring rate in the suspension drastically improves handling of the vehicle in turns, reduces wheel hop and improves weight transfer during hard acceleration. Adjustable from 0-3" drop, the coil over suspension also improves the appearance of your car by reducing fender gap between the wheel and the body of your car. Featuring hard-plastic caps to prevent shock failure and priced well below our competitors, Megan Racing coil-over kits prove you don t have to spend a fortune for high-performance and quality. (Note: Upgraded shocks are recommended for cars lowered more than 2.25")
