Wilwood 140-14113 Front Disc Brake Kit Road Race GT Rotor - FSL6R/ST

The Wilwood 140-14113 FSL6R/ST Front Disc Brake Kit is a championship-proven, dedicated road racing brake system engineered for serious competition. This complete front brake kit delivers exceptional stopping power, thermal durability, and consistent pedal feel from green flag to checkered flag.

Forged Aluminum Calipers with Thermlock® Technology:

• Forged aluminum caliper body with Type III Mil-Spec hard anodized medium gray finish for superior wear resistance in piston bores and high resistance to abrasion and corrosion
• Thermlock® pistons reduce heat transfer from pads to caliper, increasing fade resistance and extending service life by lowering temperatures in the caliper body, fluid, and seals
• Internal damper springs and controlled-retraction, high-temperature piston seals ensure consistent pedal height throughout race conditions
• Piston volumes matched for full compatibility with OE power brake boosters and master cylinders; easily configured for manual brake conversions and balance bar pedal setups

Spec37 Alloy GT Competition Rotors:

• 12.88" diameter directional vane rotors machined from Spec37 alloy for high cooling efficiency
• Rugged durability and thermal stability engineered for sustained high-heat competition environments
• Forged aluminum hats mount rotors to OE hubs, minimizing unsprung and rotating weight

Complete Bolt-On Kit Includes:

• FSL6R/ST forged aluminum calipers
• Spec37 alloy GT 12.88" directional vane rotors with forged aluminum hats
• Caliper mounting brackets with all premium-grade fasteners — mount in stock spindle location with no modifications required
• High-temperature, high-friction endurance race compound brake pads selected specifically for this application
