With our ST sport springs, you can equip your car with a spring kit that has been developed especially for your vehicle and it allows you to reach a decent lowering in combination with your standard suspension.
ST Sport Springs lower the center of gravity to reduce body roll in corners and limit weight transfer under acceleration. Manufactured to the highest worldwide quality standards, each spring is custom wound from high-tensile steel and rigorously tested and inspected to ensure absolute strength and reliability.
