Centric 128.66057L SportStop Cross-Drilled Vented Brake Rotor Front Driver Side

The Centric 128.66057L SportStop is a cross-drilled, vented, 1-piece direct-fit disc brake rotor designed for the front driver side position on 1/2-ton trucks and SUVs with 6-lug hubs. Built from a material lineage descended from the patented StopTech AeroRotor, this performance rotor delivers measurably improved stopping power for demanding street, daily driver, and autocross applications.

The application-specific cross-drill pattern is CNC-machined into the rotor face to promote efficient dispersal of heat, brake dust, and gases that can otherwise reduce pedal feel and braking consistency. In wet conditions, the cross-drilling actively channels water away from the rotor surface to maintain firm, predictable contact with the brake pad. The rotor is sold individually.

Key Features:

• Cross-drilled design: CNC-machined drilling pattern optimized for heat, gas, and brake dust evacuation
• Vented construction: Internal cooling vanes help dissipate heat during repeated or heavy braking
• Power Alloy metallurgy: Increased molybdenum content extends rotor service life, improves reliability, and helps reduce NVH (noise, vibration, and harshness)
• Superior thermal crack resistance: Material composition delivers enhanced resistance to cracking caused by thermal stress
• Prevents pad glazing: Rotor surface finish maintains consistent pad bite and braking feel over time
• Improved wet and dry performance: Cross-drilling draws moisture away from the braking surface for confident stops in all conditions
• Direct fit: 1-piece drop-in replacement for factory brake systems and stock calipers — no modifications required
• 6-lug fitment: Designed for 6-lug 1/2-ton truck and SUV applications
