Product Description

The AST Height Adjustable Lowering Spring Kit for the BMW G90 M5 sedan and G99 M5 touring delivers a performance-oriented stance and enhanced chassis dynamics with flexibility unmatched by conventional lowering springs. This system replaces the factory springs with precision-engineered adjustable units that allow you to dial in ride height between approximately 20 mm and 60 mm lower than stock, tailoring the look and feel of your vehicle to your driving style. Built to work seamlessly with adaptive electronic dampers, AST’s design maintains comfort and ride quality while sharpening steering response and reducing body roll. Fully engineered, tested, and manufactured in the Netherlands, this kit brings premium suspension customization to drivers who want improved handling and aggressive presence without sacrificing daily usability.
