The AST lowering spring set for 2001–2005 BMW 3 applications reduces ride height by 40mm front and 30mm rear to lower the center of gravity while retaining much of the OEM comfort. Built as a direct OEM replacement and cold‑coiled on Wafios machines, these progressive springs balance a lowered stance with improved handling and are backed by a lifetime warranty against breakage.
