About the StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors Line

The StopTech Select Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance through improved rotor cooling and debris evacuation. The combination of cross-drilled holes and precision slots helps reduce brake fade by allowing heat and gases to escape more efficiently. This rotor line is vented with straight vanes to maintain structural integrity while optimizing airflow, making it suitable for street and light performance driving applications.

Technical Details and Specifications

This disc brake rotor features a vented design with straight vanes that promote effective heat dissipation during braking. The cross-drilled and slotted surface improves pad bite and helps clear water, dust, and brake dust from the rotor surface. The rotor measures 10.217 inches (259.5 mm) in outside diameter and has a nominal thickness of 0.906 inches (23.000 mm), with a discard thickness of 0.827 inches (21.000 mm) to indicate when replacement is necessary. It mounts behind the hub using four bolt holes arranged on a 114.3 mm (4.5 inch) bolt circle diameter, with a center hole diameter of 3.622 inches (92.000 mm). The bolt thread pitch is 1.250 inches, and the rotor weighs approximately 11.15 lbs (5.07 kgs).

Applications and Problem Solving

• Compatible with Acura and Honda Accord and CL models requiring reliable brake rotor replacement
• Addresses brake fade caused by excessive heat buildup during aggressive or prolonged braking
• Improves braking consistency in wet or dusty conditions by evacuating water and debris
• Helps reduce brake noise and vibration through precise slot and hole placement
• Suitable for drivers seeking enhanced rotor cooling without modifying the vehicle's braking system

Installation Notes and Tips

• Ensure rotor thickness is above discard thickness (0.827 inches) before installation
• Clean rotor surface with brake cleaner to remove any protective coatings prior to mounting
• Torque mounting bolts to manufacturer specifications using the 1.250 inch thread pitch
• Inspect brake pads and calipers for wear or damage during rotor replacement
• Perform a bed-in procedure after installation to optimize rotor and pad performance
