ISC Suspension Track / Race Coilover Kit Fits 14-20 BMW 4 Series

The ISC V2 N1 Coilover Kit is a high-performance suspension system designed for street and weekend track use. It features pillowball upper mounts, 32-way adjustable damping, and separate preload and ride height adjustments. This kit includes Triple S upgraded coilover springs made from high tensile steel, offering increased stroke, fewer coils, and approximately 20% lighter weight than standard springs. The V2 version includes redesigned, sealed, and self-lubricated Japanese Koyo thrust bearings for reduced maintenance, adjustable end links (where applicable), and revised hardened spring perch isolator pads to reduce friction and extend lifespan. All adjustment locks are constructed from T6061 aluminum alloy, and front camber plates (up to 3 degrees adjustment) are also made from T6061 anodized aluminum. The system uses a single cylinder monotube damper design with high-pressure nitrogen. Each kit comes with copper-based anti-seize lubricant and ISC Coilover Covers. It is ISO and ARTC Certified and backed by a Limited Lifetime Warranty to the original owner against defects.
