Raybestos 681954PER R-300 Performance Slotted Front Brake Rotor

The Raybestos 681954PER is a high-performance slotted brake rotor designed for street performance applications. Part of the R-300 Performance line, this rotor features patented S-Groove slot technology that maximizes pad-to-rotor contact for improved braking performance and heat dissipation.

Key Features:

• Patented S-Groove slotted design maximizes pad-to-rotor contact and heat management
• Constructed from premium-grade cast iron with application-specific metallurgy
• 14-inch diameter vented rotor for front position installation
• Black Onyx coated rotor hat for enhanced appearance and corrosion resistance
• Gray Fusion 4.0 coating on inboard surfaces and cooling vanes prevents rust and improves airflow
• Cooling vanes match OE configuration for optimal performance and noise reduction
• Turned finish minimizes noise and improves brake responsiveness
• Lateral runout of 0.002 inches or less for reduced pedal pulsation
• Thickness variation less than 0.0004 inches ensures smooth, consistent braking
• Mill-balanced for vibration-free operation and extended pad life
• Meets SAE standards for tensile strength ensuring structural integrity

This performance rotor delivers enhanced pedal feel, increased pad life, and lasting rust protection. The S-Groove slot design effectively evacuates gases and debris while maintaining consistent pad contact throughout the braking cycle. Sold individually.
