ST Sport lowering spring kit for BMW E46 convertible and Sport Wagon gives a subtle, application‑matched drop while maintaining compatibility with the original dampers. Each kit is tuned with vehicle‑specific spring rates to preserve ride quality and improve handling characteristics. Constructed from chrome silicon steel with cold winding, multi‑tempering and an epoxy finish, these springs lower the center of gravity, resist sag and reduce body roll for steadier steering.
