M2/M3/M4 BASIC COILOVER KIT TRACK/

The ISC Suspension Basic Coilover Kit Track/Race with Triple S Upgraded Coilover Springs features 32-way damping adjustability (rebound/compression in unison). It includes a T6061 anodized aluminum top plate with an isolated rubber bushing for improved road compliance. The design incorporates high-rigidity steel piston rods, valved according to spring rate and dyno tested. The single-cylinder, monotube damper uses high-pressure nitrogen. The threaded shaft is powder coated and salt spray coated for durability. Springs are made from high-quality SAE 9254 steel, dyno tested over 500,000 times with less than 5% deformation; custom rates are available. Full-length height adjustability of up to 3 inches is possible, with adjustment locks made from T6061 aluminum alloy. Bound is adjustable with separate spring locks, and preload is separate from ride height. The upgraded Triple S Coilover Spring Kit, made of high tensile steel, provides increased spring stroke, improved performance due to fewer coils per spring, and is approximately 20% lighter than standard steel coilover springs. The product is ISO9001, 2000R, and ARTC certified, and comes with a lifetime warranty.
