About the C-TEK Standard Disc Brake Rotors Line

The C-TEK Standard Disc Brake Rotors line by Centric offers a balance of quality and value for standard braking applications. These rotors are designed to meet or exceed OEM specifications, providing consistent performance and fitment for vehicles like the Subaru Impreza. The vented design with pillar-style vanes enhances heat dissipation, reducing the risk of brake fade during normal driving conditions.

Detailed Product Description

This Centric disc brake rotor features a vented construction with pillar-style vanes that promote efficient airflow and cooling. The smooth surface finish ensures even pad contact and braking response. With a nominal thickness of 0.787 inches and a discard thickness of 0.709 inches, this rotor maintains structural integrity throughout its service life. The rotor’s overall height of 2.657 inches and outside diameter of 12.441 inches are engineered to match Subaru Impreza specifications precisely. The 5-lug hole pattern with a 4.5-inch bolt circle diameter and a center hole diameter of 2.283 inches ensures proper mounting and alignment. This rotor does not include an ABS tone ring or bearings, so it is intended for vehicles where these components are not required or are reused from the original assembly.

Common Applications and Problem Solving

• Replacement for worn or warped rotors on Subaru Impreza models
• Addresses brake pulsation caused by uneven rotor surfaces
• Improves braking consistency by restoring proper rotor thickness
• Helps reduce brake fade through vented design for better heat dissipation
• Suitable for routine maintenance and brake system overhauls

Installation Notes and Tips

• Verify compatibility with your specific Subaru Impreza year and trim before installation
• Inspect brake pads and replace if worn to ensure optimal rotor performance
• Clean rotor surface with brake cleaner before installation to remove any protective coatings
• Torque lug nuts to manufacturer specifications to avoid rotor warping
• Check for proper rotor thickness and discard if below 0.709 inches
