Raybestos 581032PER R-300 Specialty Street Performance Rear Disc Brake Rotor

The Raybestos 581032PER R-300 Specialty Street Performance Rear Disc Brake Rotor is engineered for drivers who demand more from their braking system. Part of Raybestos' top-tier R-300 series, this vented rear rotor is built to deliver stronger bite, smoother pedal feel, and extended pad life compared to standard replacement rotors — making it an ideal upgrade for high-performance vehicles, work trucks, and family haulers with towing demands.

Key Features:

• Patented S-Groove Slot Design: Maximizes pad-to-rotor contact surface for improved pedal feel, stronger bite, and increased brake pad life
• Grey Fusion 4.0 Coating: Applied to inboard rotor surfaces and cooling vanes, this coating is rated for 300 hours of salt spray resistance, reducing rust for optimal airflow, cooling, and aesthetics
• Black Fusion Coating: Applied to the rotor hat for a clean, finished appearance and corrosion protection
• Application-Specific Enhanced Iron: Suppresses noise and keeps brakes running cool, quiet, and vibration-free
• OE-Matched Cooling Vane Configuration: Provides optimal heat dissipation, reduced brake fade, less noise, and increased pad life
• Precision Turned Finish: Minimizes noise and improves responsiveness for smoother, more consistent stops
• Tight Tolerances: Lateral runout of 0.002 in. or less and thickness variation under 0.0004 in. for reduced pedal pulsation and extended pad life
• Mill-Balanced & 100% Validated: Ensures proper balance and minimizes thickness variation right out of the box
• SAE Standard Compliant: Meets SAE tensile strength standards using G3000-qualified material for structural integrity and maximum service life
• Sold Individually: One rotor per package
