Detailed Product Specifications

This Raybestos R-Line rotor (part number 980451R) is a vented, conventional type rotor designed specifically for Mini Cooper vehicles. The vented design enhances cooling by allowing air to flow between the rotor surfaces, reducing the risk of brake fade during extended use. The rotor's nominal thickness is 0.866 inches (22.000 mm), with a discard thickness of 0.803 inches (20.400 mm), ensuring clear service limits for safe operation. The overall height measures 1.732 inches (44.000 mm), and the outside diameter is 11.567 inches (293.800 mm), matching the Mini Cooper's brake system requirements. The rotor features four mounting bolt holes with a 3.937 inch (100.000 mm) bolt circle diameter and a center hole diameter of 2.524 inches (64.100 mm), providing precise alignment and fitment. Additionally, the rotor includes four stud/lug holes to accommodate the vehicle's wheel assembly.
