AST Lowering Spring Set BMW M5 G90/G99 Touring S68

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.

The spring rates are specifically designed for the different G90 Sedan and G99 Touring applications.
