Product Line Details: StopTech Sport Cross-Drilled Disc Brake Rotors

The StopTech Sport Cross-Drilled Disc Brake Rotors line is designed to provide enhanced braking performance through improved heat management. The cross-drilled surface pattern helps reduce brake fade by allowing gases and heat to escape more efficiently. This product line focuses on solid rotors with a coated hat finish to resist corrosion, making them suitable for both street and light track use on compatible vehicles such as the Audi A4 and A4 Quattro.

Technical Specifications and Features

This rotor features a solid design with a 245 mm outside diameter and a nominal thickness of 10 mm, ensuring durability and consistent braking force. The cross-drilled surface improves water and gas evacuation, which helps maintain pad contact and braking efficiency. The coated hat finish protects against rust and corrosion, extending rotor life. The rotor mounts using a floating disc system with a 112 mm bolt circle diameter and five 15.5 mm lug holes, matching factory specifications for the Audi A4 and A4 Quattro.

Applications and Problem Solving

• Reduces brake fade during aggressive driving or heavy braking
• Improves heat dissipation for consistent brake performance
• Minimizes water buildup on rotor surface for better wet-weather braking
• Prevents corrosion with coated hat finish for longer service life
• Restores factory braking feel and performance on Audi A4 and A4 Quattro

Installation Notes and Tips

• Ensure compatibility with Audi A4 and A4 Quattro models before installation
• Check rotor discard thickness (8.000 mm) and replace if below this limit
• Use proper torque specifications for the 5 lug bolts during mounting
• Inspect brake pads and hardware for wear when replacing rotors
• Perform a bed-in procedure after installation to optimize braking performance
