New for 2022 - Ultra high range adjustable damper allows for the use of any spring up to 50kg without rebuild and retune. Competition coilovers are short for a low ride height on OEM knuckles while PRO coilovers are longer for use with our upcoming rear drop knuckles. These have many of the best things you have come to expect from our brand like front and rear pillowball upper mounts, light weight aluminum brackets and full tap independent pre-load and ride-height adjustability. They also have high quality components and a robust damper. - True rear coilovers eliminate the stock separate spring and shock setup - 18kg/mm front spring rates, 10kg/mm rear spring rates give you a firm ride height, great for controlling a low ride height car. - Fully threaded damper & lower mount allows vehicle height to be adjusted independent of the spring preload - Custom spring rates are available to special order (4-50kg) - Pillow ball upper mount on front AND REAR allows you to change track width without binding the coilovers. Perfect for use with extended lower arms. - Spring upper perch provides independence between the spring and the pillow-ball - Billet T6061 lightweight anodized aluminum front and rear mounts, collars, perches. - Urethane bushing front lower. - Laser lettering on the damper threads for easily matching adjustments on left and right sides. - Smooth upper damper body is designed to seal against our airbag o-rings. Upgrade any time. - Progressive bump stop. *since front coilovers mount to lower control arms, changing the arm length will change ride height. We recommend using our front lower arms to achieve an extra low ride height. Helper springs are sold separately and will help you achieve a lower ride height.
