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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to offer improved braking performance for sport and performance-oriented vehicles. Featuring a combination of cross-drilled holes and precision-machined slots, these rotors enhance pad bite and help evacuate gases, dust, and water from the braking surface. The vented design with pillar-style vanes promotes consistent cooling, reducing the risk of brake fade during demanding driving conditions. This product line balances durability and performance, making it suitable for both street and light track use.

Technical Specifications and Detailed Description

This disc brake rotor is vented with pillar-style vanes that optimize airflow to maintain lower operating temperatures. The rotor’s surface is cross-drilled and slotted, which aids in heat dissipation and helps maintain consistent braking performance under stress. The coated hat finish protects against corrosion, extending the rotor’s service life. The rotor features a floating disc mounting system that allows slight movement between the rotor and hat, reducing the chance of warping and improving overall braking smoothness. With a center hole diameter of 68.000 mm and a mounting bolt hole circle diameter of 112.000 mm, this rotor fits securely on compatible Audi models with 5 lug holes of 15.200 mm diameter.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or towing
• Improves braking response and pad bite on Audi A4, A5, A6, A7, and Q5 models
• Helps prevent rotor warping caused by heat buildup
• Minimizes brake dust and debris accumulation on the rotor surface
• Extends rotor lifespan by resisting corrosion with coated hat finish

Installation Notes and Tips

• Ensure compatibility with your specific Audi model and verify lug pattern (5 lug, 112 mm bolt circle)
• Inspect brake pads and replace if worn before installing new rotors
• Torque mounting bolts to manufacturer specifications to avoid rotor distortion
• Check for ABS tone ring compatibility; this rotor does not include an ABS tone ring
• Properly bed-in new rotors and pads to optimize braking performance
