Technical Specifications and Features
This Centric disc brake rotor features a nominal thickness of 1.268 inches (32.2 mm) and a discard thickness of 1.209 inches (30.7 mm), ensuring precise wear limits for safe operation. The rotor has an outside diameter of 12.717 inches (323 mm) and an overall height of 2.051 inches (52.1 mm). It is a vented rotor with pillar-style vanes to optimize heat dissipation during braking. The rotor includes a floating disc mounting system and three miscellaneous holes for proper fitment. It is designed for vehicles with a 5-lug wheel pattern, 4.5-inch bolt circle diameter, and stud/lug hole diameter of 0.563 inches (14.3 mm). The center hole diameter measures 2.783 inches (70.7 mm). The rotor surface is smooth and fully coated, while the hat is also coated to prevent corrosion.
