The combination of Pro-Kit, respectively Sportline, with optimal standard dampers is a technically good solution, but only the combination of these spring systems with the Pro-Damper puts the finishing touch to the sports suspension.
 

These dampers basically consist of sports parts and on the outside that are similar to O.E.-production types. Based on extensive and costly simulations and driving tests of the dampers, internal components are optimally tuned to the Pro-Kit and adjusted fully compatible to Sportline.
