• OE Vane Configuration: Duplicates the original equipment vane geometry to ensure proper and maximum heat dissipation
• CNC-Machined Precision: Machined to the tightest tolerances for a guaranteed OE fit
• 100% Mill-Balanced: Precision mill-balanced for vibration-free, smooth stopping at any speed
• Non-Directional Surface Finish: Promotes faster brake pad bed-in and smoother stops from day one
