Detailed Product Description

This Power Stop rotor pair features a slotted and drilled surface type that helps reduce brake fade by allowing gases and debris to escape during braking. The vented rotor construction improves airflow, which aids in maintaining optimal operating temperatures under demanding conditions. With a precise outside diameter of 286.70 mm and a mounting bolt hole circle diameter of 114.30 mm, these rotors are designed to fit securely on front brake assemblies of compatible vehicles.

The nominal thickness of these rotors ranges between 24.50 mm and 26.30 mm, ensuring durability and consistent braking performance. The discard thickness values indicate the minimum safe thickness before replacement is necessary, helping maintain safety and reliability. This rotor set does not include a rust-resistant coating, so proper maintenance is recommended to prevent corrosion over time.
