Description
Engineered for drivers who want sharper handling without sacrificing everyday comfort, this ST X coilover suspension delivers adjustable ride height and refined damping for BMW coupes and sedans. The kit pairs application-specific dampers developed in collaboration with KW with a durable, friction-optimized polyamide composite spring perch and stainless steel insert to prevent corrosion between strut and perch. Galvanized zinc-coated steel struts, a dust protection system, and a multi-layered pressure-resistant sealing package protect internal components while the mono block guide and low-friction piston band maintain consistent damper response across road conditions.
