The AST G8X M2 / M3 / M4 Lowering Spring Set is designed for BMW owners looking to improve stance, sharpen handling response, and maintain everyday drivability. Manufactured from premium high-tensile chromium-silicone wire, each spring is carefully selected by AST engineers for material quality, strength, and consistency.
Each AST lowering spring is cold wound, heat treated, shot peened, phosphate treated, and powder coated to deliver long-term durability and performance. Before shipping, every spring is blocked and computer tested to help reduce settling once installed on the vehicle.
AST Suspension brings decades of motorsport experience into every product, with development and testing rooted in demanding environments such as the 24h Nürburgring, Pikes Peak, Classic Le Mans, and BMW racing programs. Every component is engineered, tested, and manufactured in the Netherlands by the AST X MOTON team.
