The AST lowering spring set for BMW 3 Series (2006–2013) lowers ride height by 40mm front and 25mm rear while preserving much of the OEM comfort. Cold‑coiled on Wafios coiling machines and designed as a direct OEM replacement, these progressive springs reduce center of gravity for improved handling. Vehicle‑specific tuning and premium construction balance a lowered stance with everyday comfort, and a lifetime warranty covers breakage.
