AST BMW G87 M2 / G80 M3 / G82 M4 Adjustable Lowering Springs

Dial in the stance of your BMW with AST adjustable lowering springs for the G87 M2, G80 M3 and G82 M4. This height-adjustable spring kit lets you fine-tune your ride height while retaining compatible factory Adaptive M dampers and OEM Electronic Damper Control (EDC).

Choose a subtle drop or a more aggressive stance within the kit’s adjustment range. With 20–46mm of front lowering and 10–36mm of rear lowering, you can tailor the front-to-rear balance instead of committing to the single ride height of a fixed lowering spring.

Why choose AST adjustable lowering springs?

• Adjustable ride height: Fine-tune the drop at the front and rear to suit your preferred stance.
• Factory damper compatibility: Designed to work with compatible Adaptive M factory dampers and OEM EDC.
• Matched spring rates: Optimized front and rear spring rates for improved driving dynamics.
• Less wheel gap: Lower the body for a more purposeful appearance without replacing the entire damper system.

Common questions

Will I retain factory EDC?

This kit is compatible with Adaptive M factory dampers and OEM EDC on the listed applications, allowing you to retain the compatible electronic damping system.

How is this different from fixed lowering springs?

Fixed springs provide a preset drop. AST adjustable lowering springs let you select a ride height within the specified front and rear lowering ranges.

Is this a complete coilover kit?

No. This is an adjustable lowering spring system intended to work with compatible factory dampers. It does not replace them with a complete coilover damper assembly.
