Wilwood 120-16460 Forged Narrow Superlite Disc Brake Caliper - 4R

The Wilwood 120-16460 Forged Narrow Superlite 4R is a high-performance four-piston radial mount disc brake caliper engineered for racing and high-performance street applications. This lightweight forged caliper features an innovative body design that removes unnecessary bulk while improving brake cooling and actually reducing deflection under extreme braking loads.

Key Features:

• Four Thermlock® thermal barrier pistons significantly reduce heat transfer to brake fluid, maintaining consistent pedal feel during extended hard braking
• Staggered bore design provides more even pad engagement and improved pad wear characteristics
• Hard-anodized Type III aluminum-oxide ceramic finish inside piston bores and on exterior surfaces for exceptional durability and corrosion resistance
• Single-point bleed technology with low-profile bleed screws simplifies bleeding and maintenance
• No-bind pad retaining pin system with spare pin included for easy pad changes
• Accepts multiple 0.80-inch thick Wilwood race compound brake pads for extended service life and customizable performance
• Radial mounting configuration for rigid, precise caliper positioning

This caliper's complex forged body shape optimizes structural rigidity while maximizing airflow around the caliper and brake fluid passages, helping manage heat in demanding applications. The combination of thermal management features and lightweight construction makes this an ideal choice for road racing, track days, and serious street performance builds.
