Technical Specifications and Features

This disc brake rotor features a vented design with straight vanes to optimize airflow and heat dissipation during braking. The rotor’s nominal thickness is 1.173 inches (29.8 mm), with a discard thickness of 1.102 inches (28.0 mm), indicating the minimum thickness before replacement is necessary. The overall height measures 1.819 inches (46.2 mm), and the outside diameter is 12.012 inches (305.1 mm), matching the Jaguar S-Type’s original rotor dimensions. The rotor includes five stud/lug holes with a diameter of 0.555 inches (14.1 mm) arranged on a 4.252 inch (108 mm) bolt circle diameter. The center hole diameter is 2.795 inches (71 mm). This rotor does not include an ABS tone ring or bearings and features a smooth surface type for consistent pad contact.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Jaguar S-Type vehicles
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves heat dissipation to reduce brake fade during extended use
• Restores proper rotor thickness to maintain braking efficiency
• Eliminates noise and vibration related to damaged or undersized rotors

Installation Notes and Tips

Ensure the rotor thickness is measured before installation to confirm it meets or exceeds the discard thickness of 1.102 inches (28.0 mm). Clean the rotor surface and hub mounting area to prevent uneven contact. Use proper torque specifications for the five lug nuts on the 4.252 inch (108 mm) bolt circle. Since this rotor does not include bearings or an ABS tone ring, verify compatibility with your vehicle’s existing components. It is recommended to replace brake pads simultaneously to ensure optimal braking performance.
