10005272 Drilled And Slotted Rotors
Immediate, consistent braking in all conditions
The unique cross-drilled or slotted finish is another exclusive GRTECH feature which improves braking consistency by dissipating the heat generated and gas released as the pads come into contact with the discs, keeping the pad surface both cool and clean.
Both cross drilling and slots interrupt the water film forming when driving in the wet for improved brake response.
This effect is most evident with cross-drilled discs, due to the different solid/hollow ratio of the surface and the possibility for water to flow through the ventilation holes.
