AST lowering springs for Audi A4 (Aug 2015–Oct 2019) reduce ride height by 40mm front and rear to lower the car’s center of gravity while preserving much of the OEM ride comfort. They’re a direct OEM-replacement set, cold‑coiled on Wafios machinery from premium materials with a progressive rate that balances a lowered stance and improved handling, plus a lifetime breakage warranty.
