MAX PRO coilovers for 1997-2013 Corvette C5 and C6. ~ Eliminates OEM transverse leaf springs and converts to a true coil-over-damper. Coilovers allow easier tuning and adjustment, as well as opens up a huge variety of spring setups ~Ultra high range adjustable dampers allow damper tuning with the turn of a knob. 32 reference clicks give a wide range of damper tuning appropriate for different spring rates and driving styles. ~ Overall coilover length is adjustable with our threaded damper bodies and mounts. This allows ride height to be adjusted independently of the helper springs and spring preload. ~Standard Springs are lightweight Japanese linear springs with 20kg/mm front spring rate and 10kg rear spring rate (approx 1120 lb/in front and 560 lb/in rear) standard, but wide range of spring rates are available by request. ~ Long stroke shocks for more useable travel and more oil volume front and rear are possible due to our unique top mounts ~Upper and lower mounts are spherical bearing to allow shocks to pivot when suspension is adjusted without binding ~Microcellular progressive bump stops ~ Lightweight anodized aluminum collars, spring perches and upper mounts. Steel lower mounts. ~You can change from coil springs to progressive air spring over dampers (air bags) at any time for more traction and response to high frequency bumps and unparalled smoothness and anti bottom out character, perfectly paired with our simple static bag lines and fittings as seen on the shop C7 filled with nitrogen, or electronic management of your choice.
