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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on performance-oriented rotors that combine cross-drilled holes and precision slots. This design improves brake pad bite and helps evacuate heat and debris more efficiently than standard rotors. The vented construction further aids in cooling, making these rotors suitable for spirited driving and daily use on compatible Saab and Subaru vehicles.

Technical Specifications and Features

This disc brake rotor features a nominal thickness of 0.945 inches (24.000 mm) and a discard thickness of 0.866 inches (22.000 mm), ensuring a durable lifespan before replacement is necessary. The rotor’s outside diameter measures 11.555 inches (293.500 mm), with an overall height of 2.228 inches (56.600 mm). It includes a coated hat finish to protect against corrosion and a floating disc mounting system to accommodate thermal expansion and reduce warping. The rotor is vented with straight vanes to optimize airflow and cooling during braking. It fits vehicles with a 5-lug pattern, 0.508 inch (12.900 mm) stud diameter, and a 100 mm (3.937 inch) bolt circle diameter.

Compatible Vehicles and Applications
