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. 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. - 12kg/mm front spring rates, 8kg/mm rear spring rates give you great steering response, with good rear grip thats controllable past the limit in drifting. - 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 mount - 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.
