Choosing your rotor face
Drilled gives the pad a fresh edge to bite on with every revolution, helps push water off the disc face in the wet, and vents the gases a hot pad gives off. It is also the classic look through an open wheel.
Slotted keeps the casting continuous, so there is more uninterrupted material in the disc under sustained heat, and the slots sweep glaze off the pad face as it wears in. Cars that see repeated hard stops or track days generally end up on slotted; street and show builds often prefer drilled.
Type-1 vs Type-3 is slot geometry, not a performance grade. Type-1 runs longer, shallower-angled slots; Type-3 a shorter, more frequent pattern. Choose on appearance - most owners match the rear to whatever they chose up front.
All three rotor faces are available to order at Rev Auto Club. Select your rotor face above.
