About the C-TEK Standard Slotted Disc Brake Rotors Line
The C-TEK Standard Slotted Disc Brake Rotors line by Centric is designed to meet or exceed OEM specifications for standard replacement rotors. Featuring a slotted surface, these rotors help improve braking performance by allowing gases and debris to escape, reducing brake fade. The vented design with curved vanes enhances heat dissipation, which is critical for maintaining rotor integrity and consistent braking under demanding conditions. This product line is suitable for drivers seeking reliable, direct-fit rotors for their Porsche 911 or Panamera.
Detailed Product Description
This Centric disc brake rotor (part number 226.37040) is a vented rotor with a slotted surface, specifically engineered for Porsche 911 and Panamera models. The vented design incorporates curved vanes that promote airflow through the rotor, helping to dissipate heat generated during braking. The slotted surface improves pad bite and assists in removing brake dust and gases, which can otherwise reduce braking efficiency.
The rotor measures 12.992 inches (330 mm) in outside diameter and has an overall height of 2.953 inches (75 mm). It maintains a nominal thickness of 1.102 inches (28 mm) with a discard thickness of 1.024 inches (26 mm), ensuring it meets precise wear limits for safe operation. The rotor mounts using five lug holes with a diameter of 0.610 inches (15.5 mm) and a bolt circle diameter of 5.118 inches (130 mm). The center hole diameter is 3.858 inches (98 mm), designed for a floating/dih disc mounting style.
Common Applications and Problem Solving
- Replacement for worn or warped rotors on Porsche 911 and Panamera models
- Addresses brake fade caused by overheating during aggressive driving
- Improves braking response by reducing pad glazing and debris buildup
- Restores proper rotor thickness to maintain braking safety and performance
- Helps eliminate vibration or pulsation caused by uneven rotor surfaces
Installation Notes and Tips
- Ensure rotor thickness is above discard thickness (1.024 inches) before installation
- Clean rotor surface and hub mounting area to prevent runout and vibration
- Use proper torque specifications for lug nuts to avoid rotor warping
- Inspect brake pads and replace if worn to optimize rotor performance
- Check compatibility with ABS systems; this rotor does not include an ABS tone ring
