Wilwood 140-14965 Forged Superlite 6R Front Race Big Brake Kit - Anodized Calipers, Slotted Rotors

The Wilwood 140-14965 Forged Superlite 6R Front Race Big Brake Kit is engineered specifically for unrestricted category road racing, delivering championship-proven stopping power with 17" or larger diameter wheels. This complete front big brake kit pairs six-piston FSL6R/ST calipers with 12.88" directional vane GT competition rotors for maximum thermal performance under sustained race conditions.

FSL6R/ST Six-Piston Caliper Features:

• Forged aluminum caliper body with Type III Mil-Spec hard anodized medium gray finish for superior durability
• Hard anodized piston bores provide outstanding wear resistance and high resistance to abrasion and corrosion
• Thermlock® pistons reduce heat transfer from brake pads to increase fade resistance and extend seal and fluid service life
• Internal damper springs and controlled-retraction, high-temperature piston seals deliver consistent pedal height throughout the race
• OE-compatible piston volumes for direct compatibility with the stock power brake booster and master cylinder; also easily adapted to manual brake conversions and balance bar pedal setups

Spec37 Alloy GT Competition Rotor Features:

• 12.88" diameter directional vane rotors in Spec37 alloy GT competition series construction
• Dynamically mounted to OE hubs using weight-saving forged aluminum hats to reduce unsprung and rotating mass
• High cooling efficiency with rugged durability and thermal stability under sustained high-heat competition conditions

Complete Kit Contents:

• Forged Superlite 6R/ST six-piston calipers (pair)
• 12.88" Spec37 alloy directional vane slotted rotors with forged aluminum hats
• Radial mount caliper brackets with all premium-grade fasteners — installs to OE spindle location with no modifications required
• BP-30 high-temperature, high-friction endurance race compound brake pads, selected specifically for this application
• Stainless steel braided brake flexlines

This big brake kit mounts in the stock caliper location without any modifications to the vehicle's spindles or suspension. The result is a race-ready front braking system that offers shorter stopping distances, improved brake modulation, a firmer pedal, and dramatically reduced brake fade — all within the demands of the most grueling production car road racing categories.
