Designed as a vented disc brake rotor, it offers enhanced heat dissipation and corrosion resistance for consistent stopping power.

  • Vented disc brake rotor design for improved heat management
  • Rust resistant Geomet coating to extend rotor life
  • Nominal thickness of 29.00 mm with discard thickness at 27.50 mm
  • Overall height of 54.80 mm and outside diameter of 305.00 mm
  • Mounting bolt hole circle diameter of 127.00 mm with 6 lug holes

Detailed Product Features and Specifications

This Power Stop rotor (part number AR8649EVC) features a vented design that helps dissipate heat more effectively than solid rotors, reducing the risk of brake fade during extended use. The rotor’s Geomet coating provides a rust-resistant surface, which is especially beneficial for vehicles exposed to moisture and road salt. With a nominal thickness of 29.00 mm and a discard thickness of 27.50 mm, this rotor maintains structural integrity and performance throughout its service life. The overall height measures 54.80 mm, and the rotor has an outside diameter of 305.00 mm, making it compatible with specific front brake assemblies on select SUVs and trucks.
