Dinan's design keeps the factory Electronic Damper Control shocks in place and implements threaded collars to allow the user to change the ride height. The end result is a sleek lowered stance that provides improved handling to go along with its stunning visual appearance. The springs combined with progressive bump stops and other components increase travel that allows the car to be lowered up to a 1.25" (1.125" on the M6). Suspension packers are included to fine-tune handling and comfort by changing the clearance of the progressive bump-stops something no respectable racecar is without. Components are machined from 6061-T6 aluminum and black anodized for appearance and corrosion protection.
