Why slotted discs?
The edges of the slots continuously clean and refresh the pad surface. This will allow the pads to have a maximized friction surface always available. Additionally, they prevent containments from collecting between the pad and disc interface. The disc is lightened, decreasing its rotational inertia. Slots prevent the formation of a water film on the disc in wet weather, maintaining the best brake response. Plain Disc · A plain disc is generally superior for dry track duty and competition use due to the maximum surface area and disc mass for maximum heat absorbing capability. · A plain disc has the least chance of cracking and warping due to having no potential stress risers and hot or cold spots on the disc face. · Discs are also available unplated, for quicker bedding. However, unplated discs are not corrosion resistant. A note on drilled discs: Girodisc does not recommend drilled discs for high performance applications. The rapid heating and cooling cycles will cause cracking on the
