ST Suspension Coilover Kit by KW for BMW Z4 E85/E86 — Overview

A height-adjustable coilover kit from ST Suspension, built on KW internals, developed specifically for the E85 Z4 Roadster and E86 Z4 Coupe. The kit drops ride height between 1.0 and 2.5 inches across all four corners independently, using a threaded strut housing with zinc plating for long-term corrosion resistance - relevant given the Z4's exposed undercarriage on a sports car platform. Matched spring and damper rates are tuned as a system rather than generic rates, and integrated rising-rate elastomeric bump stops replace the stock rubber units for more controlled compression at the limit of travel. ST by KW is a well-regarded entry point into the KW family for E-chassis owners who want European damper engineering without the full KW Variant price.
