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 during braking. The vented rotor construction with straight vanes enhances airflow, reducing the risk of brake fade under demanding conditions. The coated hat finish provides corrosion resistance, making these rotors suitable for both street and light track use.

Technical Specifications and Compatibility

This disc brake rotor features a nominal thickness of 0.880 inches (22.350 mm) and a discard thickness of 0.815 inches (20.700 mm), ensuring a durable service life before replacement is necessary. The overall height measures 1.890 inches (48.000 mm), and the outside diameter is 9.685 inches (246.000 mm). It is designed without ABS tone rings and does not include bearings. The rotor mounts using a floating disc system with a center hole diameter of 2.299 inches (58.400 mm) and a 5-lug hole pattern with 0.520 inch (13.200 mm) diameter holes on a 3.937 inch (100.000 mm) bolt circle diameter.
