With this set of Height Adjustable Lowering Springs, you’re not limited to a fixed lowering range. Thanks to the precision-engineered AST height adjuster, you can fine-tune your ride height even after installation, giving you full flexibility and control. The AST Adjustable Lowering Springs lower your vehicle’s centre of gravity while maintaining the comfort and refinement of the original suspension. Developed as a direct OEM replacement, each kit is specifically designed for your BMW model and crafted from premium materials using advanced Wafios coiling machines. The progressive spring design ensures the perfect balance between a lower, more aggressive stance and enhanced handling dynamics. Proudly made in the Netherlands, Europe.
