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 performance by combining cross-drilled holes and precision slots. This design improves heat dissipation and helps remove brake dust and gases from the rotor surface, which can improve pad bite and reduce brake fade. The vented rotor construction further aids in cooling, making these rotors suitable for both street and light performance driving. The coated hat finish adds durability by protecting against rust and corrosion, extending rotor life.

Detailed Product Description

These disc brake rotors feature a vented design with straight vanes that promote airflow to maintain optimal operating temperatures. The cross-drilled and slotted surface pattern enhances braking consistency by allowing gases and debris to escape, which helps maintain clean pad contact. The floating disc mounting system accommodates thermal expansion, reducing the risk of warping under heavy braking conditions. With a center hole diameter of 2.906 inches (73.800 mm) and five lug holes sized at 0.524 inches (13.300 mm), these rotors are engineered to fit securely on compatible Jaguar models. Weighing approximately 19.07 lbs (8.67 kgs), they balance durability and performance.

Common Applications and Problem Solving

• Reduces brake fade during aggressive or prolonged braking
• Improves heat dissipation to prevent rotor warping
• Helps maintain consistent brake pad contact by removing dust and gases
• Protects against corrosion with coated hat finish
• Enhances braking performance on Jaguar Vanden Plas, XJ8, XJR, and XK8 models

Installation Notes and Tips

• Ensure rotor discard thickness of 1.024 inches (26.000 mm) is not exceeded before replacement
• Verify compatibility with vehicle make and model before installation
• Use proper torque specifications for the five lug nuts on the 120.700 mm bolt circle
• Inspect brake pads and calipers during rotor replacement for optimal performance
• Clean rotor surface before installation to remove any protective coatings or debris
