ST Sport lowering spring kit for BMW Z3 coupe and roadster (non‑M) provides a subtle, application‑matched drop while using the factory dampers. Each set is tuned with vehicle‑specific spring rates to maintain proper suspension function and improved dynamics. Built from chrome silicon steel in a cold winding process, multi‑tempered and epoxy coated, the springs resist sag and reduce body roll for steadier cornering.
