ISC Suspension Street Sport Coilover Kit Fits 06-07 BMW 5 Series

The ISC Suspension Basic Coilover Kit Street Sport features 32-way damping adjustability for rebound and compression. It uses a T6061 anodized aluminum top plate with an isolated rubber bushing for improved road compliance. The design incorporates high rigidity steel piston rods and a monotube damper with high-pressure nitrogen for enhanced stability. The threaded shaft is powder-coated and salt spray coated for durability. The kit includes ISC Springs made from high-quality SAE 9254 steel and Triple S Upgraded Coilover Springs, which are approximately 20% lighter than standard springs, offering increased spring stroke and improved performance. The coilovers provide up to 3 inches of full-length height adjustability, with preload separate from ride height to maintain consistent ride quality. The product is ISO9001, 2000R Certified, and ARTC Certified, and comes with a lifetime warranty to the original purchaser against defects in workmanship and material. ISC Suspension recommends a 5mm preload on all corners.
