AST lowering spring set for Audi S4 and A4 from 1998 reduces the center of gravity while preserving much of the OEM ride comfort, producing a firmer stance with a 25mm front and 15mm rear drop. Cold-coiled on Wafios machines and supplied as a vehicle-specific direct OEM replacement, the progressive springs balance lowered appearance and improved handling. Compatible across many models and backed by a lifetime warranty against breakage.
