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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to provide enhanced braking performance through improved heat management and surface friction. The combination of cross-drilled holes and precision-machined slots helps to evacuate gases, dust, and water from the rotor surface, maintaining consistent pad contact and reducing brake fade. This product line is suitable for performance-oriented vehicles like the Ford Mustang, where reliable stopping power and rotor durability are critical.

Product Details and Specifications

This disc brake rotor is vented with pillar-style vanes that promote airflow to cool the rotor during heavy braking. The floating disc mounting allows for slight movement between the rotor and hat, accommodating thermal expansion and reducing the risk of warping. The coated hat finish protects against corrosion, which is especially beneficial in environments exposed to moisture and road salts. The rotor’s dimensions, including a 330 mm outside diameter and 28 mm nominal thickness, are matched to Ford Mustang brake systems requiring a 5-lug bolt pattern with a 114.3 mm bolt circle diameter.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or track use
• Improves heat dissipation to prevent rotor warping
• Maintains consistent braking performance in wet conditions
• Minimizes brake dust buildup for cleaner rotor surface
• Extends rotor service life with corrosion-resistant coating

Installation Notes and Tips

Ensure compatibility with your specific Ford Mustang model before installation. The rotor does not include bearings or an ABS tone ring, so verify existing components are compatible. Proper torque specifications should be followed when mounting the rotor to the hub using the 5-lug pattern. It is recommended to inspect brake pads and calipers during installation to ensure optimal braking system performance.
