Detailed Product Description and Specifications

This disc brake rotor features a 305 mm outside diameter and a nominal thickness of 25 mm, with a discard thickness of 23 mm to indicate when replacement is necessary. The rotor is vented to allow airflow through the disc, reducing heat buildup during braking. The surface is both drilled and slotted, which aids in gas and dust evacuation, improving braking response and reducing brake fade. The directional surface design ensures optimal contact with brake pads for consistent stopping power.

The rotor’s hat is finished in zinc black, providing a rust-resistant coating that helps protect against corrosion. It includes five bolt holes with a diameter of 12.5 mm arranged on a 114.3 mm bolt circle diameter, matching the stud/lug hole pattern for secure mounting. The center hole diameter is 69 mm, ensuring proper fitment on the hub.

Compatible Vehicles and Common Applications

• Replacement rotor for Hyundai Elantra and Sonata models
• Suitable for Kia K5 and Niro EV brake system upgrades
• Compatible with Hyundai Kona and Kona Electric for enhanced braking
• Addresses issues such as brake fade, rotor warping, and uneven pad wear
• Improves heat dissipation and braking consistency under demanding conditions

Installation Notes and Tips

Ensure the rotor thickness is measured before installation; replace if below the discard thickness of 23 mm. Clean the rotor surface to remove any protective coatings before mounting. Verify bolt hole alignment with the vehicle’s hub and torque lug nuts to manufacturer specifications. Directional rotors must be installed with the correct rotation direction for optimal performance.
