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 have a longer design to work well with a higher, more functional ride height. These will not go low unless paired with our drop knuckles. If you want to go low, we suggest the Competition coilover model. - True rear coilovers eliminate the stock separate spring and shock setup - 18kg/mm front spring rates, 8kg/mm rear spring rates. Lightweight linear springs made with japanese high tensile alloy. - Longer stroke dampers for more usable suspension travel. 40mm longer rear compared to Competition coilovers. - Fully threaded damper & lower mount allows vehicle height to be adjusted independent of the spring preload and without using a helper spring - Custom spring rates are available to special order (4-50kg) - Pillowball upper mount on front AND REAR allows you to change track width without binding the coilovers. - Spring top hat provides independence between the spring and the pillowball - Anodized aluminum rear mounts, collars, perches. Steel front lower mounts. - 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. *We recommend using our lower arms to achieve a very low ride height. Since front coilovers mount to lower control arms, you can lengthen the track width to achieve a very low ride height. The Pro coilovers are longer than comp for use with drop knuckles.
