Schumacher peripheral touring car dampers

The Schumacher peripheral damping system has been developed for touring cars to help minimise tyre contact patch load fluctuations, caused by small bumps in the track surface. This means the tyre remains in contact with the ground more often, resulting in more grip and improved lap times. The damping characteristic is dependent upon the position of the piston within the shock body. The damping is softest when the piston is at the bottom of the shock, at which point the peripheral volume is at its greatest. Conversely the damping is hardest when the shock is at the top of the body, and the sleeve has the smallest opening. As a consequence of this, the damping characteristic progressively increases with bump/roll, compared to the kit damper assembly which offers linear damping throughout the damping stroke. The dampers are supplied in pairs to fit the Schumacher Mi5evo, but will also fit other touring cars on the market. Spare parts are available separately to update current Mi5evo shocks.
