ROTOR STYLE: Contact Surface treatment 2
0010010 nbsp;So-called plain rotors have smooth contact surfaces, and this is what is found on most OE rotors. However, you 0010010 #39;ll find that plain rotors can also function well as performance rotors. They just don 0010010 #39;t necessarily look as cool as a 0010010 quot;treated 0010010 quot; surface.
0010010 nbsp;Slotted rotors feature indented, shallow slots cut into both sides of the rotor faces. These slots allow more water, heat, brake dust, and friction gases to slide out from underneath the pads. Because slotted rotors stay cooler, they 0010010 #39;re ideal for aggressive driving and 4WDs that haul heavy loads or tow trailers. Since the slots are not deeply cut into the rotor, there is minimal risk of the disc cracking. 0010010 nbsp;
