• Front drilled and slotted surface for improved heat and gas dissipation
• Zinc plated coating to resist rust and corrosion
• Vented rotor design for better cooling during braking
• Nominal thickness of 25.00 mm with discard thickness at 23.00 mm
• Overall diameter of 300 mm and outside diameter of 11.80 inches
• Mounting bolt hole circle diameter of 114.30 mm with 5 lug holes

Detailed Product Features and Specifications

This Power Stop rotor pair features a vented design that helps maintain optimal braking temperatures by allowing air to flow through the rotor. The front drilled and slotted surface improves brake pad bite and helps evacuate brake dust and gases, reducing brake fade during demanding driving conditions. The zinc plating provides a protective layer against rust, extending the rotor's service life, especially in humid or wet environments.

With a nominal thickness of 25.00 mm and a discard thickness of 23.00 mm, these rotors meet the specifications required for safe and effective braking. The overall height measures 47.30 mm, and the rotor's outside diameter is 300 mm (11.80 inches), ensuring proper fitment and compatibility with the specified Acura and Honda models. The mounting bolt hole circle diameter is 114.30 mm, accommodating 5 lug holes with a 4.50 mm diameter.
