These Power Slot Brake Rotors are a direct replacement for Mazda 6 Rear rotors on all 2006-07 models. Power Slot rotors are manufactured to the highest tolerances keeping safety and quality their number one priority. Slotting, unlike drilling, doesn't compromise the structural integrity of the rotor. When you drill a rotor you weaken it and cause stress points that can lead to cracking and ultimately failure. Also, drilled rotors lose considerable surface area compared to slotted rotors, which means less active braking area for pad to rotor contact.
Heat is the primary cause of ineffective brakes due to fade. There is actually a "boundary layer" of gases that builds up between the pad and rotor surface, which inhibits performance. Here's where Power Slot rotors make a big difference. The exclusive Vac-U-Slots machined into the rotor "wipes" brake pads clean, evacuates gases, and sheds heat. A combination of a "high performance pad" and Power Slot rotors will provide superior reliable braking for virtually all automotive and truck applications, with an upgrade to larger diameter rotors and bigger calipers typically only needed for the most severe competition applications.
Power Slot's Mazda 6 brake rotors are made using high quality Original Equipment replacement blanks. Many competitors will sacrifice quality by using inexpensive offshore castings, which can be 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. The exclusive Power Slot 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.
