The Eibach Progressive Tender Springs are designed to function appropriately with a stiffer linear main spring in order to generate a smoother initial spring rate. They are coiled from flat wire to effectively compress and bind up into a small disc shape. Once these springs are completely compressed, an ideal final rate is established. With their consistent spring rate, users are certified that their suspension will function at an elevated level. A systematic control upgrade is also bestowed for reliability during those stressful racing conditions.
