Centric 128.66045L SportStop Cross-Drilled Vented Brake Rotor Rear Left

The Centric 128.66045L SportStop is a cross-drilled, vented disc brake rotor designed for the rear driver side. Built as a direct-fit replacement, it delivers a meaningful upgrade over OEM braking performance for street driving and autocross applications alike.

Manufactured from a material that is a direct descendant of the patented StopTech AeroRotor alloy, this rotor features an elevated molybdenum content for enhanced hardness, extended service life, and reduced noise, vibration, and harshness (NVH). The cross-drilled pattern is CNC-machined using an application-specific layout, ensuring drilled holes never intersect cooling vanes — a critical design detail that significantly reduces the risk of thermally induced cracking.

Key Features:

• Cross-drilled, directional design CNC-machined for this specific application
• Vented construction for improved heat dissipation and fade resistance
• Increases initial pad bite and prevents pad glazing
• Effectively channels water away from the rotor surface for improved wet-weather braking
• Elevated molybdenum content extends rotor reliability and service life
• Superior resistance to thermal stress cracking
• Direct-fit replacement — no modifications required
• 6-lug hub pattern
• Compatible with Limited Slip Axle applications
• Sold individually
