The AST lowering spring set for BMW 3 Series (2006–2013) lowers ride height by 45mm front and 30mm rear while preserving much of the OEM comfort. Cold‑coiled on Wafios coiling machines and supplied as a direct OEM replacement, these progressive springs reduce center of gravity for improved handling response. Vehicle‑specific tuning and premium materials balance lowered stance and daily comfort, and a lifetime warranty protects against breakage.
