Technical Details and Specifications

This Centric rotor features a vented design with straight vanes that promote airflow and heat dissipation, reducing the risk of warping under heavy braking. The smooth surface type ensures even brake pad wear and consistent friction. The rotor mounts behind the hub with six mounting bolt holes arranged on a 6.748-inch (171.400 mm) bolt circle diameter. The discard thickness is 1.320 inches (33.530 mm), indicating the minimum thickness before replacement is necessary. The hat-shaped design contributes to structural integrity and proper alignment during installation.

Common Applications and Problem Solving

• Replacement for worn or warped rotors causing brake pulsation
• Upgrading from solid to vented rotors for improved heat management
• Addressing uneven brake pad wear due to rotor surface irregularities
• Restoring braking performance on vehicles with 15-inch rotor requirements
• Ensuring proper fitment with 6-bolt mounting patterns behind the hub

Installation Notes and Tips

Ensure the rotor thickness is above the discard thickness of 1.320 inches (33.530 mm) before installation. Clean the mounting surface and hub to prevent runout and ensure proper rotor seating. This rotor is designed to mount behind the hub using six bolts, so verify bolt hole alignment and torque specifications according to the vehicle manufacturer’s guidelines. No ABS tone ring or bearings are included, so confirm compatibility with your vehicle’s braking system.
