The AST lowering spring set for Audi TT (1998–2006) reduces ride height and lowers the vehicle’s center of gravity while retaining much of OEM ride comfort as a direct replacement. This kit drops about 25mm front and 25mm rear, is cold‑coiled on Wafios coiling machines and features progressive rates to balance stance and handling. It’s covered by a lifetime warranty against breakage for long‑term reliability.
