Product Description

The AST Suspension ASTALS-21-004 Adjustable Lowering system is a vehicle-specific performance suspension upgrade designed to transform the stance, handling, and driving dynamics of 2021-2023 BMW M2, M3, and M4 models. Unlike fixed lowering springs, this adjustable system allows enthusiasts to dial in the exact ride height they desire while maintaining compatibility with the factory Adaptive M suspension and electronic damping control (EDC). With a broad range of adjustability - 20-46 mm front and 10-36 mm rear - this kit helps lower the center of gravity for improved cornering, reduced body roll, and more aggressive aesthetics without sacrificing daily drivability.

Engineered for both street and performance use, the AST ALS springs are made from high-tensile steel with optimized spring rates that complement the balance of comfort and performance expected in high-end sports cars. Direct replacement for the original springs, this kit offers a plug-and-play installation using OEM mounting points and retains all factory suspension functions. Fitment is confirmed through 2023; 2024 and 2025 coverage is currently unconfirmed at time of listing.
