Slotted rotors for your RX-8 are a top choice for more efficient and reliable braking with cooler operating temperatures and extended service intervals.
During both normal and hard braking on your RX8, gasses from friction & heat are released from the brake pad's surface. As the RX-8 brake rotor slots moves across the pad, the gases are allowed to escape, similar to water under a tire tread. This allows the pad to generate more friction without added pedal effort. At the same time, abrasive particles that would normally be trapped between the brake rotor & pad surface are wiped off the pad and collected in the slots. As the slot moves away from the pad the particles are released. This aids cooling and helps extend pad and brake rotor life on your RX8.
Proper installation for RX-8 Trak Pro slotted brake rotors is achieved as follows: when rotating forward, the outer end of the slot on the brake rotor leads or moves ahead of the slot's inner end. Forward rotation on the left side is counter clockwise & forward rotation on the right side is clockwise, assuming you're looking at the outside face of the wheel in question.
