Wilwood 140-16092 Forged Narrow Superlite 6R Front Big Brake Kit Race 12.88in Slotted Rotor

The Wilwood 140-16092 Forged Narrow Superlite 6R Front Big Brake Kit is purpose-built for dedicated road racing, delivering race-proven stopping power through a complete, bolt-on brake upgrade. This kit is engineered specifically for vehicles originally equipped with 54mm piston calipers and requires 17-inch or larger wheels with additional inside clearance to accommodate the upgraded brake package.

FNSL6R/ST Six-Piston Radial Mount Calipers:

• Forged aluminum caliper body with Type III Mil-Spec hard anodized medium gray finish for maximum durability
• Hard anodized piston bores provide superior wear resistance and high abrasion and corrosion resistance throughout the caliper
• Thermlock® pistons reduce heat transfer from brake pads to the caliper, extending seal and fluid service life and improving fade resistance
• Internal damper springs and high-temperature, controlled-retraction piston seals maintain consistent pedal height throughout a race session

GT Competition Series Rotors:

• Spec37 alloy, 12.88-inch diameter directional vane slotted rotors for maximum thermal stability and sustained high-heat performance
• Dynamically mounted to OE hubs using weight-saving forged aluminum hats to minimize unsprung and rotating mass
• Directional vane design delivers high cooling efficiency and rugged durability under competition conditions

Complete Race-Ready System Includes:

• Application-matched, high-temperature, high-friction endurance compound race brake pads
• Caliper mounting brackets with all premium-grade fasteners for stock-location installation — no modifications required
• All hardware needed for complete front brake assembly

Note: Stainless steel braided brake flexlines are required for installation and must be ordered separately by vehicle year, make, and model. OEM replacement fitment: replaces 54mm piston front calipers.
