StopTech 126.34031SR Sport Rotors are slotted for improved cooling, better fade resistance, quicker wet weather response, and enhanced aesthetics. StopTech brake discs are 100% machine finished, including rotor hats, to optimize rotor balance and give a cleaner, more finished looking component. A Black e-coating is applied on non friction surfaces for added corrosion protection.

StopTech Sport Rotors feature a High Carbon metallurgy (in most applications) for quieter operation, better crack resistance and increased performance. StopTech Sport Rotors are OEM diameter for a perfect replacement fit and offer OE or improved vane design where possible on all rotors. StopTech brake discs are double disc ground for a consistent friction surface with improved bed in and are mill balanced for zero vibration.
