Power Slot Brake Rotors - 1994-02 Miata - Rear (Except Sport Package Brakes with 10.9" rear discs.* (Priced and sold as pairs) - Heat is the primary cause of ineffective braking performance. During repeated braking a "boundary layer" of gases builds between the pad and rotor surface, reducing braking efficiency and performance. Here's where Power Slot rotors make a big difference. The exclusive Vac-U-Slots machined into the rotor surface "wipes" brake pads clean, evacuates gases, and improves heat dissipation. A combination of high performance brake pads and Power Slot rotors will provide superior and reliable braking for all Miata applications, with an upgrade to larger diameter rotors and bigger calipers typically only needed for the most severe competition applications.
Power Slot rotors are well-suited for use on any daily-driven Miata and perform best when used with an ungraded aftermarket performance pad. We recommend Hawk's HPS compound for use with these rotors as they provide excellent braking performance, low noise, and virtually no dust.
Power Slot rotors are made using the highest quality Original Equipment replacement blanks. Competitors will sacrifice quality by using inexpensive off-shore castings. Typically these are made of inferior porous material and often have less cooling fins than their OE counterpart. These fins also serve to reinforce the rotor and guard against warpage. Power Slot rotors always meet and/or exceed all OE specifications. It's also important to know that the exclusive Vac-U-Slot is tapered to enhance evacuation of heat and gases. All machining is done in house to Power Performance Group's application specific tolerances to ensure optimum quality control.
*All 1994-00 Miatas are equipped with standard (10.0" front/9.9" rear) disc brakes. For the 2001-2002 model year, Mazda offered a larger brake package (10.6" front/10.9" rear) on models with factory installed 16"wheels (included on cars with the Sport Suspension package). The larger brake package became standard on all 2003-05 Miatas. If you question the size of the brakes on your car, we suggest you measure the diameter of the disc for reference.
