AST Suspension Lowering Springs for 2021-2024 BMW M4 & M440i xDrive (30mm/30mm) ASTLS-21-182
This product will be available for sale in 2 weeks, but you can pre-order now to receive 10% discount!
Fits 2021-2024 BMW M4 (Base, Competition, Competition xDrive, CSL) and M440i xDrive Base.
AST Suspension lowering springs are engineered to reduce your vehicle's center of gravity for improved cornering performance and a more aggressive stance, all while retaining the ride quality of the factory dampers. These springs are designed as a direct replacement for OEM units, utilizing the original mounting points for a precise, bolt-on installation.
Manufactured on high-precision Wafios coiling machines, these springs feature a progressive rate design. This allows for a compliant ride during normal driving while becoming firmer under load to reduce body roll and pitch. Each spring is crafted from premium materials to ensure consistent performance under the stresses of spirited driving.

- Spring Type: Progressive rate design
- Construction: Cold-coiled on Wafios coiling machines
