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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line focuses on delivering rotors that combine cross-drilled holes and precision slots to enhance braking efficiency. This design helps to evacuate heat, brake dust, and gases generated during braking, which is critical for maintaining consistent brake performance. The vented construction with straight vanes further aids in cooling, making these rotors suitable for both street and light performance driving applications.

Technical Details and Compatibility

These rotors feature a vented design with straight vanes to optimize airflow and heat dissipation. The coated hat finish provides corrosion resistance, helping to maintain rotor integrity over time. The floating disc mounting system allows for slight movement between the rotor and hub, reducing the risk of warping under heavy braking conditions. With a center hole diameter of 2.756 inches (70.000 mm) and five lug holes sized at 0.559 inches (14.200 mm), these rotors are engineered to fit specific Chevrolet Astra, Saab 9-3, Saab 9-5, and Saturn models precisely.

Common Applications and Problem Solving

• Reduces brake fade during extended or aggressive braking
• Improves heat dissipation to prevent rotor warping
• Minimizes brake dust buildup for cleaner braking surfaces
• Enhances wet weather braking performance by channeling water away
• Restores braking efficiency on vehicles with worn or damaged rotors

Installation Notes and Tips

Ensure the rotor surface and hub mounting area are clean and free of debris before installation. Verify the rotor thickness is within the discard limits (minimum 0.866 inches or 22.000 mm) to maintain safety and performance. Use proper torque specifications for the five lug bolts and confirm compatibility with your vehicle’s ABS system, as these rotors do not include an ABS tone ring. It is recommended to replace brake pads simultaneously to optimize braking performance.
