Product Details

BMW has tuned a comfortable yet performance oriented suspension system across their model offering.  The springs used are a very sophisticated design with both tapered wire diameter and progressive spring rates to ensure the best possible ride quality under varying loads and conditions.  Due to environmental conditions, the original coating is commonly compromised thus creating a weak point which yields to failure (cracked springs).

Thankfully, ECS Tuning and Suplex have a cost-effective, high-quality solution. Suplex is a world-renowned supplier of springs for many original equipment manufacturers. They utilize the finest spring steel and best manufacturing techniques possible to ensure quality. The springs are wound on state-of-the art CNC spring winding equipment, then shot-peened and stress treated for maximum strength, before a zinc phosphate coating is applied beneath the final epoxy powdercoat to ensure unparalleled corrosion resistance. Sold each – ECS Tuning recommends that you replace the springs in pairs (front and rear) for best performance.
