June 18, 2025

Get rid of that wheel gap for a solid price. What's the pricing and quality like? As new suspension solutions emerge for the G90 M5, AST Suspension leads the way with its premium Adjustable Lowering Spring (ALS) Kit, designed specifically for drivers who want the freedom to fine-tune ride height without compromising factory ride quality. Unlike traditional fixed-drop springs, the AST ALS Kit allows for precise, independent height adjustment—perfect for adapting to regional road conditions or individual preferences. The system offers a maximum lowering range of 45mm up front and 37mm in the rear, delivering a more aggressive stance while maintaining full compatibility with BMW’s Adaptive M Suspension system. Developed and manufactured entirely in the Netherlands under one roof, AST’s kit reflects a commitment to engineering excellence and long-term durability. Each system is backed by a lifetime warranty against breakage, giving owners peace of mind with every mile.
