StopTech Power Slot 12-13 Audi A6 Quattro/11-12 A7 Quattro / 10-13 S4 Rear Right Slotted Rotor
StopTech Slotted Sport Rotors are 1-piece direct replacement brake discs for factory brake systems and stock calipers that look great behind your wheels – and offer significantly improved braking performance. The unique slotting aids with heat and brake dust dispersal; prevents glazing of the pads; adds bite and improves wet and dry braking performance. Built to last; the black e-coating provides protection from corrosion and the high carbon metallurgy (in most applications) offers quieter operation; better crack resistance and increased performance.
Premium rotor with advanced metallurgy that greatly reduces pad squeal. Especially effective with higher friction; European style brake pad compounds. Slotted for increased bite; improved looks and better performance

Excessive heat can cause resins in your brake pad to vaporize or "outgas." As the brake pad wears, the used friction material turns into a fine dust. This boundary layer of heat, gas and dust builds up between the pad and rotor surfaces and inhibits performance. Here's where StopTech SportStop slotted brake rotors make a big difference. StopTech SportStop Slotted Brake Rotors are a true performance rotor and feature:
⢠Power Alloy castings (on select applications)
⢠Engineered Performance Rotor
⢠Superior resistance to cracking due to thermal stress
⢠Increased molybdenum (higher carbon)content that extends reliability, service life and helps reduce NVH ânoiseâ issues
⢠Rotor material is a direct descendant of the patented AeroRotor from StopTech
⢠Introducing directional curve vane design (on select applications)
⢠Improved vane design or OE equivalent on all rotors
⢠Center split castings
⢠New short slot design runs perpendicular to the vane to preserve rotor strength.
⢠Direct OE Replacement
⢠Improved wet weather response
⢠Increased initial âbiteâ
⢠Double disc ground for a consistent friction surface and Improved pad bed-in
⢠Mill balanced
⢠Black E-Coated non-friction surfaces on âPower Alloyâ rotors
⢠Enhances open wheel appearance
