AST lowering springs for Ford Sierra (1988–1993) reduce the car's center of gravity while retaining much of the OEM ride comfort. Built as direct OEM replacements and cold‑coiled on Wafios machines, the progressive spring rates balance a lowered stance with enhanced handling. Vehicle‑specific construction uses premium materials and is covered by a lifetime warranty against breakage, with broad compatibility since 1966.
