The AST Adjustable Lowering Springs for the 2020+ Toyota GR Supra A90 and BMW Z4 G29 offer an ideal solution for drivers who want improved stance, sharper handling, and full compatibility with the factory Electronic Damper Control (EDC) system. Unlike fixed-height springs, AST’s adjustable design allows precise ride height tuning to achieve the perfect balance between aesthetics, performance, and everyday drivability.
This system pairs high-quality linear-rate springs with threaded adjustable perches, giving owners the ability to fine-tune the drop at each corner. Whether you want a subtle reduction or a more aggressive lowered stance, the AST kit delivers predictable control and uniform adjustability without sacrificing shock travel or ride quality.
AST engineered these springs specifically for chassis equipped with factory adaptive dampers. The system retains full EDC functionality, ensuring that Comfort, Sport, and adaptive damping modes continue working exactly as intended. This means you gain improved agility and reduced body roll while preserving daily comfort and OEM refinement.
Manufactured from high-strength spring steel and tested to motorsport durability standards, the AST kit is built to withstand aggressive street use and spirited driving. The springs are finished in a corrosion-resistant coating, and the adjustable spring perches are precision-machined for smooth, reliable height adjustments.
