Optimize the suspension of Bavaria's premium sport touring coupe, the G8X BMW M3/M4, with AST Suspension's Lowering Springs. Lowering the center of gravity reduces body roll, improving cornering stability. The progressive spring rates maintain ride quality, and compatibility with OE dampers and Electronic Damping Control ensures a seamless application. The springs are manufactured from high-tensile chromium-silicone wire, chosen by AST Suspension's engineers for its quality and consistency. Each spring is cold wound, then heat treated to increase hardness and reduce internal stress, and before shipping, is blocked and tested to reduce settling after installation, so the height is right from the start.
AST Lowering Springs are manufactured from a premium high tensile chromium-silicone wire which is handpicked by AST engineers for its quality and metal consistency. Each spring is cold wound and then heat treated to increase hardness and reduce internal stresses present after winding. Each spring is then individually shot-peened, phosphate treated and then powder coated to outlast even the life of the vehicle.
