Question about this product?

We're happy to help.

The AST G8X M2 / M3 / M4 Adjustable Lowering Spring Kit is engineered for enthusiasts who want precise control over ride height without sacrificing the functionality of the factory suspension system. Unlike traditional lowering springs with a fixed drop, AST Height Adjustable Spring (HAS) systems allow you to fine-tune ride height even after installation, giving you the flexibility to dial in both stance and performance.

Designed to work seamlessly with factory adaptive and electronic dampers, this system maintains all OEM comfort and driver assistance features while enhancing overall driving dynamics. Similar in concept to a coilover system, the AST HAS kit provides a continuous adjustable lowering range, allowing for a more aggressive stance and improved handling characteristics without negatively impacting ride quality.

AST Suspension brings decades of motorsport experience into every product, with development and testing rooted in demanding environments such as the 24h Nürburgring, Pikes Peak, and various BMW racing programs. Every component is engineered, tested, and manufactured in the Netherlands by the AST X MOTON team, ensuring a high level of precision, durability, and performance.
