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

The StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on delivering enhanced braking performance through precision-engineered rotors featuring cross-drilled holes and slots. This design improves pad bite and helps evacuate heat and debris, which is critical for trucks and SUVs like the Cadillac Escalade and Chevrolet Tahoe that require dependable braking under varied driving conditions. The vented rotor construction further aids in maintaining optimal operating temperatures during extended braking.

Technical Specifications and Features

These rotors feature a vented design with straight vanes to promote airflow and heat dissipation. The overall height measures 3.362 inches (85.400 mm), and the center hole diameter is 3.091 inches (78.500 mm), ensuring precise mounting. The mounting bolt hole circle diameter is 5.500 inches (139.700 mm) with six stud/lug holes sized at 0.650 inches (16.500 mm). The rotors do not include ABS tone rings or bearings, so these components must be sourced separately if required.
