MAX PRO True Coilovers for 2008+ Hyundai Genesis Coupe BK1 and BK2 ~ Ultra high range adjustable damper allows for the use of any spring up to 50kg without rebuild and retune. ~PRO coilovers are longer than Comp coilovers to allow more useable travel and higher ride height. ~Pro coilovers feature a rotatable camber/caster plate instead of a standard camber plate. ~ Eliminates OEM separated rear spring and shock and converts to a true coilover for easier adjustment and more spring setup options. ~Standard 10kg/mm front spring rates, 6kg/mm rear spring rates give you great steering response, with good rear grip thats controllable past the limit in drifting. Wide range of other spring rates available by request ~ Fully threaded damper & lower mount allows vehicle height to be adjusted independent of the spring preload ~ Pillow ball upper and lower mounts 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 ~ Lightweight anodized aluminum front and rear mounts, collars, perches. ~ Laser lettering on the damper threads for easily matching adjustments on left and right sides. ~ Microcellular progressive bump stops ~ Can be upgraded at any time to our Air Springs for $900 (airbags) **INSTALL NOTES: We recommend only using the OEM front swaybar endlinks to prevent binding and damage to the links and mounts. Compatible with early and late model endlinks. *Hole must be drilled in rear trunk liner to access top of shock for damper adjustment. *Remove stock rear springs and shocks and leave them out. Only install the coilovers. Now that true coilovers are installed, you have the option of installing our adjustable rear lower control arms, sold separately.
