Wilwood 140-14114 FSL6R/ST Front Road Race Disc Brake Kit with HD Rotors

The Wilwood 140-14114 FSL6R/ST Front Road Race Disc Brake Kit is purpose-built for production-category road racing where regulations permit brake system upgrades while restricting modifications to six-piston calipers and 12.88" rotors. This competition-grade front kit delivers the stopping consistency and thermal durability required for sustained track use.

FSL6R/ST Calipers: The Forged Superlite 6R/ST calipers feature a Type III hard anodize finish for maximum corrosion resistance and surface durability. Thermlock pistons are incorporated to dramatically reduce heat transfer from the brake pads into the caliper body, fluid, and seals — resisting brake fade and extending overall service life during extended high-temperature racing conditions.

HD Series Directional Vane Rotors: The 12.88" HD series directional vane rotors are engineered for high cooling efficiency, channeling airflow through the rotor to dissipate heat rapidly under hard braking. These rotors mount securely to the hubs via forged aluminum GT hats, combining lightweight construction with the strength needed for competition environments.

Key Features:

• Six-piston FSL6R/ST calipers with Type III hard anodize finish
• Thermlock pistons reduce heat transfer and resist brake fade
• 12.88" HD series directional vane rotors for superior thermal management
• Forged aluminum GT hats for lightweight, rigid rotor mounting
• High-temperature race compound brake pads included
• Stainless steel braided flexlines for consistent pedal feel
• Premium grade installation hardware included
• Designed for use with 17" and larger diameter wheels
• Configured for production-category road racing regulations

This complete front brake kit includes everything needed for installation: race compound pads, stainless steel flexlines, and all required hardware. It is designed to fit 17-inch and larger wheels, making it an ideal upgrade for competitors seeking a compliant, high-performance braking solution within production-class racing rules.
