Centric 128.42041L SportStop Cross-Drilled Vented Disc Brake Rotor - Front Left

The Centric 128.42041L SportStop Brake Disc is a cross-drilled, vented front left rotor engineered for drivers who demand more from their braking system. Built from a high-performance iron alloy that is a direct descendant of the patented StopTech AeroRotor material, this rotor delivers enhanced bite, improved fade resistance, and long-term reliability for street performance and autocross applications.

Application-specific cross-drilling patterns are CNC-machined into the rotor face to optimize heat dissipation, reduce brake dust buildup, and expel gases that can cause pad glazing. The vented construction further improves thermal management by allowing continuous airflow through the rotor, helping to maintain consistent braking feel under repeated hard stops. In wet conditions, the drilled channels actively draw water away from the rotor surface for more confident, responsive braking.

Key Features:

• CNC-machined cross-drilled pattern for optimized gas, heat, and dust evacuation
• Vented disc construction for improved thermal cooling and fade resistance
• Iron alloy derived from the patented StopTech AeroRotor for superior strength
• Increased molybdenum content for extended service life and reduced NVH (noise, vibration, and harshness)
• Prevents pad glazing and increases initial pad bite
• Superior resistance to cracking caused by thermal stress
• Improved wet and dry braking performance
• Direct-fit replacement — no modifications required
• Sold individually
• 4-lug fitment

Performance is further maximized when paired with Centric Street Performance brake pads. Backed by Centric's 90-day or 3,000-mile limited warranty.
