Product Description

Give your G8X-platform BMW M2, M3, or M4 a precise, race-inspired stance with the AST Adjustable Lowering Spring Kit. These height-adjustable springs replace the restrictive, fixed drop of conventional lowering springs with a fully tunable system, letting you dial in ride height anywhere within a wide range even after installation — no coilovers required. AST’s thoughtfully engineered spring rates and adaptive suspension compatibility maintain your vehicle’s dynamic balance while lowering center of gravity for improved handling, sharper turn-in, and a more aggressive profile. Designed to work with both standard and Adaptive M factory dampers, this kit delivers performance and attitude without compromising everyday drivability.
