Product Line Details: StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking performance by combining cross-drilled holes and precision slots. This design improves heat dissipation and helps evacuate gases and debris from the rotor surface, which is critical for maintaining consistent braking under demanding conditions. The vented rotor construction further aids in cooling, making these rotors suitable for trucks and SUVs that require reliable stopping power during towing or heavy-duty use.

Technical Specifications and Compatibility

This disc brake rotor features a vented design with straight vanes to optimize airflow and cooling. The rotor's coated hat finish provides corrosion resistance, helping maintain structural integrity over time. It includes an ABS tone ring to ensure seamless integration with the vehicle's anti-lock braking system. The rotor measures 295 mm (11.614 inches) in outside diameter, with a nominal thickness of 32.7 mm (1.287 inches) and a discard thickness of 30.86 mm (1.215 inches). The mounting bolt hole circle diameter is 127 mm (5 inches), with 5 lug holes and a stud thread diameter of 14 mm, ensuring a precise fit for Chevrolet and GMC models such as the C1500, Tahoe, and Yukon.
