KONI Special (red or black). The KONI Special dampers are designed to offer the best compromise between road handling and comfort. If only a Special damper is listed, its adjustment forces are designed for all driving requirements. KONI Sport (yellow). The KONI Sport dampers are designed for aggressive driving or cars with suspension upgrades while continuing to offer comfort. If a KONI Sport is listed as an alternative to the KONI Special, choose Sport for aggressive handling characteristics. KONI Sport (yellow) shocks are identified by the Sport suffix (example, 8040-1026 Sport). KONI Special (red or black) shocks are listed without the Sport suffix (example, 8040-1026). --- Q: What is the difference between KONI Special (red) and KONI Sport (yellow)? A: The KONI Special (red) has been engineered to maximize the ride comfort with good handling performance for each vehicle application. The KONI Sport (yellow) typically starts at a higher initial valving baseline to give a sportier feel and work on vehicles with higher performance parts. In some instances, KONI will only offer a Special or Sport valving and not both. Some modern cars come from the factory with higher tech suspension systems and wheel/tire packages so they would move directly into the Sport range, however they are still valved to give a comfortable ride with very good handling capabilities. quelle: http://www.tirerack.com/suspension/
