Product Description

The AST ASTALS-21-001 Adjustable Lowering Springs are designed for BMW F8X M2, M3, and M4 models, providing adjustable ride-height control without requiring replacement of the factory dampers. The height-adjustable spring-seat design allows the vehicle's stance to be fine-tuned after installation, making the system suitable for drivers who want a lower center of gravity while retaining factory-style damper functionality.

The progressive spring design is engineered to balance improved handling with everyday drivability. The kit covers the F87 M2, F80 M3, and F82/F83 M4 platforms with 3.0L turbocharged inline-six engines and rear-wheel drive. Vehicle-specific lowering varies by application, with an approximately 15-45 mm front and 10-33 mm rear adjustment range reported for the kit.

This kit is intended for BMW enthusiasts seeking adjustable lowering for street, performance, or track-oriented applications. Verify the specific chassis, suspension configuration, and factory damper compatibility before installation, particularly when selecting between pre-LCI and LCI F80/F82 configurations.
