• Compatible with 5-lug stud pattern and 12.835 inch (326 mm) outside diameter

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

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is designed to enhance braking performance for sport and luxury vehicles. This product line features rotors with cross-drilled holes and precision slots that help maintain consistent brake pad contact and reduce gas buildup during heavy braking. The vented rotor construction with straight vanes improves airflow, which helps maintain optimal operating temperatures. The coated hat finish provides additional protection against rust and corrosion, making these rotors suitable for both daily driving and spirited use.

Technical Specifications and Features

This disc brake 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 durable lifespan before replacement is necessary. The overall height measures 1.508 inches (38.3 mm), and the center hole diameter is 2.531 inches (64.3 mm). It features a 5-hole mounting bolt pattern with a 4.252 inch (108 mm) bolt circle diameter and 0.551 inch (14 mm) stud/lug hole diameter. Weighing approximately 15.15 lbs (6.89 kgs), this rotor balances strength and weight for reliable braking performance.

Applications and Problem Solving

• Reduces brake fade during high-performance or heavy braking conditions
• Improves heat dissipation to prevent rotor warping and extend component life
• Helps maintain consistent brake pad contact for smoother stopping power
• Minimizes brake dust and debris buildup on rotor surface
• Resists corrosion with coated hat finish for longer service intervals

Installation Notes and Tips

Ensure compatibility with your Jaguar model by verifying the 5-lug stud pattern and rotor dimensions before installation. The floating disc mounting design requires proper torque specifications to allow for thermal expansion. It is recommended to replace brake pads simultaneously to optimize braking performance. Always inspect related components such as wheel bearings and calipers during installation, as this rotor does not include bearings or ABS tone rings.
