• Pad glazing from elevated rotor temperatures
• Brake dust buildup on the rotor face
• Corrosion on exposed rotor surfaces
• Reduced wet-weather braking response

Installation Notes

Install on the rear left position only and verify rotor dimensions, bolt pattern, and hub fitment before assembly. This rotor is listed for stock calipers and factory brake systems, so confirm the vehicle’s rear disc size and application notes before purchase. Brake pads should be inspected and replaced if wear or glazing is present, and the braking system should be cleaned and torqued to manufacturer specifications during service.

Quality Assurance

The coated finish helps resist corrosion, and the high-carbon construction used in most applications supports quieter operation and improved crack resistance. StopTech’s Sport Cross-Drilled Disc Brake Rotors are engineered as direct replacement brake discs for street use with factory-style braking systems.
