The AST lowering spring set for BMW 4 xDrive models built between March 2014 and July 2021 lowers ride height and reduces the car’s center of gravity while preserving much of OEM comfort. These vehicle‑specific springs are cold‑coiled on Wafios machines and feature a progressive wind to balance a lowered stance and handling. Supplied as direct OEM replacements, they include a lifetime warranty against breakage and match thousands of compatible applications.
