Centric 128.42041R SportStop Cross-Drilled Vented Brake Rotor Front Passenger Side

The Centric SportStop 128.42041R is a cross-drilled, vented brake disc engineered for drivers who demand confident stopping power on the street and at autocross events. Sold individually, this direct-fit rotor installs on the front passenger side and is designed as a bolt-on upgrade over a standard replacement disc.

Manufactured from a cast iron alloy that is a direct descendant of the patented StopTech AeroRotor material, the 128.42041R features an increased molybdenum content that extends rotor reliability, prolongs service life, and helps reduce noise, vibration, and harshness (NVH). The result is a rotor that holds up under repeated thermal cycling without sacrificing everyday drivability.

Key Features:

• CNC-machined cross-drilled pattern — application-specific drilling optimizes gas, dust, and heat evacuation from the rotor surface
• Vented disc construction — internal vanes promote airflow to dissipate heat buildup during aggressive braking
• Improved wet-weather performance — cross-drilling effectively channels water away from the friction surface for consistent bite in all conditions
• Prevents pad glazing and increases overall pad bite for a more responsive pedal feel
• StopTech AeroRotor-derived metallurgy — elevated molybdenum content enhances thermal crack resistance and long-term durability
• Direct-fit replacement — no modifications required for a straightforward installation
• Compatible with 4-lug hub applications
• Pairs ideally with Centric Street Performance Brake Friction pads for a matched high-performance brake system

The Centric SportStop 128.42041R is backed by a 90-day or 3,000-mile Centric limited warranty. For best results and maximum performance gains, replace brake pads at the same time as rotors and bed in the new brake components according to Centric's recommended break-in procedure.
