Koni cellular polyurethane bump rubbers are specially designed to protect the suspension from bottoming. Like a progressive spring, the bump rubber resistance increases the more it is compressed. This not only provides safe and controlled bottoming of the suspension, but it also prevents internal damage within the shock from metal-to-metal contact.

Koni FSD shock absorbers combine the benefits of performance and comfort into one package. The FSD (Frequency Selective Dampening) shocks are firm for control over long bumps and corners, but soft for comfort over expansions joints and rough roads. These shock components have an extra valve that controls oil flow parallel to the piston assembly, giving the vehicle a smooth ride. At low frequencies, FSD shocks are able to make a significantly greater amount of force than conventional shocks—which controls bouncing, body roll, and brake drive. During high frequencies, the shocks generate dramatically lower forces for a smoother ride over rough roads. Easily added to any vehicle, Koni FSD shock absorbers are the first to offer the performance of an electronic system in a patented, completely integrated, non-electronic package. Take performance and driving comfort to the next level with the installation of Koni FSD shock absorbers on your vehicle.

Koni SPA1 drag race shocks work differently than the 90/10 shocks you're probably used to seeing. Rather than letting the front rise quickly and stay up during launch, Koni's front shocks allow the front-end to rise quickly and then settle down faster to reduce front-end drag and improve your ETs. These shocks have five settings to help you tune your chassis. Koni's rear shocks help keep your rear-end planted by stiffening up as you run over surface irregularities, minimizing rebound and keeping the tires on the track. These shocks are for drag racing only; they are not designed for highway use.

Koni STR.T suspension kits consist of high performance STR.T shocks, struts, and precisely fitting lowering springs. Koni's entry-level performance STR.T (pronounced Street) shocks and struts bring improved handling and Koni quality to the budget-minded driving enthusiast. Whether to simply refresh and upgrade a stock vehicle or to match with other modifications, Koni STR.T provides performance at a value price point. Both companies can look back on many years of experience in motor racing, such as in Formula 1 or the DTM. The advantages for the customer are obvious. The experience gained along with the technological developments flow directly into the companies' product development. Koni's STR.T. shock absorbers stand for perfect road holding, optimum handling, and breathtaking centrifugal force. Thanks to the extremely high reaction speeds of the shock absorbers, drivers can totally rely on their equipment—even in precarious or demanding situations. As a result of the symbiosis between lowering springs and Koni's STR.T shocks into the STR.T Kit, tuners receive a suspension kit from the factory that's perfectly balanced to suit their vehicle. Unpleasant pitch and rolling movements are thus reduced to a minimum. Depending on vehicle make, a lowering up to 40mm is offered. This means that nothing now stands in the way of high-speed drives on curving roads and the ultimate driving pleasure.
