Super quiet sport slotted brake rotors feature a narrow profile slot pattern. This helps your pads stop and degas under load and speed, while eliminating air noise. Coated with a black zinc finish, Ultimax slotted rotors come complete with bearing cups where fitted as OEM and are sold and priced in sets for either front or rear. The price you see is for (2) two rotors, one left and one right. Another great feature of slotted rotors is the way the pads remain flat and have uniform pad wear, while also avoiding the record grooves or galling common with non-slotted rotors. This improves pad contact and braking throughout the life of the rotor and pad set.
