ISC Suspension 03-09 BMW X3 E83 N1 Street/Sport V2 Coilover Kit

The ISC V2 N1 coilover is designed for improved handling on street or weekend track cars. It features a single cylinder monotube design with 32-way adjustable damping, allowing for fine-tuning of ride quality and performance. Preload adjustment is separate from ride height adjustment, ensuring that lowering the vehicle does not compromise ride comfort. The springs are made from high-quality SAE9254 steel, tested over 500,000 times with less than 5% deformation. The kit comes standard with pillowball upper mounts and camber plates (when applicable). It is ISO and ARTC Certified and backed by a Limited Lifetime Warranty to the original owner. New V2 features include redesigned thrust bearings with lower stack height and sealed self-lubricated Japanese Koyo bearings for reduced maintenance, as well as updated adjustable end links (where applicable) and revised hardened spring perch isolator pads for reduced friction and extended product lifespan.
