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

The StopTech Sport Cross-Drilled Disc Brake Rotors line focuses on performance-oriented rotors that balance durability and heat management. The cross-drilled design helps to evacuate gases and water from the rotor surface, which is critical for maintaining braking efficiency during spirited driving or in wet conditions. This rotor’s vented construction with straight vanes further aids in cooling, making it suitable for Jaguar models that demand consistent brake performance.

Technical Specifications and Features

This rotor has a nominal thickness of 0.783 inches (19.9 mm) and a discard thickness of 0.709 inches (18.0 mm), ensuring a solid lifespan before replacement is necessary. The overall height measures 1.508 inches (38.3 mm), and the outside diameter is 12.835 inches (326 mm). It features a coated hat finish to protect against corrosion, and the center hole diameter is 2.531 inches (64.3 mm). The rotor is designed for a 5-stud lug pattern with a 0.551 inch (14 mm) stud hole diameter and a 108 mm mounting bolt hole circle diameter. Weighing approximately 15.15 lbs (6.89 kg), this rotor balances strength and weight for optimal vehicle dynamics.

Common Applications and Problem Solving

• Reduces brake fade during high-performance or extended braking
• Improves heat dissipation to prevent rotor warping
