AST lowering springs for BMW 5 (March 1997–May 2004) reduce ride height by about 35mm while keeping much of the OEM comfort. Built as vehicle‑specific direct OEM replacements, they’re cold‑coiled on Wafios coiling machines and shaped with progressive rates to balance a lowered stance and improved handling. These springs are backed by a lifetime warranty against breakage.
