AST Suspension Lowering Springs (30mm/25mm) - 2009-2018 BMW Z4 Roadster 35i/35is (E89)

AST Lowering Springs for the 2009-2018 BMW Z4 (E89) 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.

• EDC Compatible (if applicable to vehicle)
• Each spring is blocked and computer tested prior to shipping, which reduces any settling once installed on the vehicle.
