StopTech Sport Cross-Drilled Disc Brake Rotors Product Line

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on delivering enhanced braking performance through advanced rotor surface technology and vented designs. The cross-drilled pattern improves heat and gas evacuation, reducing brake fade during aggressive driving. The vented rotor with straight vanes promotes consistent airflow to maintain optimal operating temperatures. This product line is tailored for drivers seeking improved brake response and durability without compromising OEM fitment standards.

Technical Details and Specifications

This disc brake rotor features a vented design with straight vanes to optimize cooling efficiency. The cross-drilled surface helps dissipate heat and brake gases, which can improve braking performance during spirited driving or track use. The rotor’s coated hat finish provides corrosion resistance, extending service life. With an overall height of 39.6 mm (1.559 inches) and a center hole diameter of 70.1 mm (2.76 inches), it fits precisely on the Honda S2000 hub. The floating disc mounting system allows slight movement to reduce stress and warping under thermal expansion. The rotor weighs approximately 6.59 kg (14.5 lbs), balancing durability and weight considerations.

Common Applications and Problem Solving

• Reduces brake fade caused by excessive heat buildup
• Improves brake pad bite and response on Honda S2000
• Minimizes rotor warping and vibration during heavy braking
• Enhances cooling to extend brake component lifespan
• Prevents corrosion on rotor hats for longer durability

Installation Notes and Tips

• Ensure compatibility with Honda S2000 models before installation
• Check rotor thickness and discard limits (nominal thickness 25.0 mm, discard at 23.0 mm)
• Use proper torque specifications for the 5 lug bolts on the 114.3 mm bolt circle
• Inspect brake pads and calipers for wear during rotor replacement
• Follow manufacturer guidelines for bedding-in new rotors and pads
