Centric 128.34066L SportStop Cross-Drilled Vented Brake Rotor - Rear Driver Side

The Centric SportStop 128.34066L is a cross-drilled, vented brake disc engineered for drivers who demand improved braking performance on the street and at autocross events. Sold individually, this direct-fit rear driver-side rotor is precision-manufactured to deliver consistent, reliable stopping power in both wet and dry conditions.

Centric SportStop rotors are crafted from a high-grade iron alloy that is a direct descendant of the patented StopTech AeroRotor material. The increased molybdenum content in the alloy extends rotor reliability, prolongs service life, and helps reduce noise, vibration, and harshness (NVH). The result is a rotor with superior resistance to cracking caused by thermal stress — a critical advantage under repeated heavy braking.

Key Features:

• Application-specific cross-drilled pattern CNC-machined for optimized gas, dust, and heat dissipation
• Vented disc construction promotes airflow and thermal management
• Effectively channels water away from the rotor surface for enhanced wet-weather braking
• Prevents glazing of brake pads and increases pad bite
• Direct descendant of the patented StopTech AeroRotor material
• Elevated molybdenum content reduces NVH and extends service life
• Superior resistance to thermal stress cracking
• Direct-fit replacement — no modifications required
• 5-lug application
• Natural finish
• Sold individually

For maximum performance, Centric recommends pairing these SportStop rotors with Centric Street Performance Brake Friction pads. Backed by a 90-day or 3,000-mile Centric limited warranty.
