AST lowering springs for BMW 4 (from July 2021) reduce ride height by 25mm front and rear while retaining much of the comfort expected from OEM springs. They act as vehicle-specific direct OEM replacements, cold-coiled on Wafios machines with a progressive rate to balance a lowered stance and improved handling. Backed by a lifetime warranty against breakage for long-term reliability.
