Description
Give your BMW 6 Series Convertible F12 a lower, more planted stance with AST Lowering Springs. Part number ASTLS-21-050 is engineered specifically for the BMW 6 Series 640/640d Convertible F12 2010-2018.
AST designs each spring set around the specific chassis it fits, so your BMW 6 Series Convertible F12 sits lower and handles with less body roll while keeping a ride quality close to the factory setup. The progressive rate absorbs everyday bumps and stiffens as the suspension compresses, giving a more planted feel through corners and under braking. AST springs are cold-coiled from premium spring steel on Wafios coiling machines in the Netherlands for consistent, accurate spring rates, and every set is backed by a lifetime warranty against breakage.
