Weighing approximately 16.9 lbs (7.68 kg), this vented rotor balances durability and performance.

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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking efficiency and thermal management for performance-oriented driving. The combination of cross-drilled holes and precision slots helps to evacuate heat, brake dust, and gases generated during braking. This design reduces the risk of brake fade and maintains consistent pedal feel, making it suitable for both street and light track use. The vented rotor construction further aids in cooling, while the coated hat finish improves corrosion resistance, extending the rotor’s service life.

Applications and Problem Solving

• Reduces brake fade during aggressive or repeated braking
• Improves heat dissipation to maintain consistent braking performance
• Minimizes brake dust buildup on rotor surface
• Helps prevent rotor warping caused by thermal stress
• Enhances braking response for Audi A3, Volkswagen Golf, Jetta, and related models

Installation Notes and Tips

• Ensure compatibility with your vehicle’s make and model before installation
• Inspect brake pads and replace if worn to maximize rotor performance
