AST ASTLS-22-122 Lowering Springs, BMW 4 Series 420i/430i/420d Coupe G22 2020+ (Excl. AWD)

Description

Enhance the handling and appearance of your BMW 4 Series Coupe G22 with a set of AST Lowering Springs. AST ASTLS-22-122 is designed to fit the BMW 4 Series 420i/430i/420d Coupe G22 2020+.

AST Lowering Springs bring the center of gravity of your BMW 4 Series Coupe G22 down without giving up the everyday comfort of the factory springs. A progressive spring rate keeps the ride compliant over normal roads while firming up under load, which reduces body roll in corners and nose dive under braking. Each spring is vehicle-specific and drops straight into the factory mounting points. 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.
