AST Height-Adjustable Lowering Springs | BMW F90 M5 (2018–2023)

AST Height-Adjustable Lowering Springs

BMW F90 M5 | 2018–2023

Lower your BMW F90 M5 while maintaining control over the final ride height with the AST Height-Adjustable Lowering Spring Kit. Unlike traditional lowering springs with a fixed drop, this system includes AST height adjusters that allow the vehicle’s ride height to be fine-tuned after installation.

Developed specifically for the F90 M5, these springs reduce the vehicle’s center of gravity for a more aggressive stance and improved handling while preserving the comfort and functionality of the factory suspension system.

The progressive spring design provides a balanced combination of everyday ride quality, reduced body movement, and increased performance during spirited driving. Each spring is manufactured in the Netherlands using premium materials and precision Wafios coiling equipment.
