AST Suspension Lowering Springs for the 2012-2018 BMW X5 (F15) will lower that center of gravity without giving in a lot of the comfort you are used to with the OEM springs. The lowering springs are a direct replacement of the OEM springs and have been developed especially for each specific vehicle. Made out of the best material on the best Wafios coiling machines available.

AST Suspension 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.
