Wilwood 120-16054 Forged Narrow Superlite Six-Piston Brake Caliper - 6R

The Wilwood Forged Narrow Superlite 6R/ST (FNSL6R/ST) represents the latest evolution in high-performance brake caliper technology. Designed for extreme high-temperature racing and performance applications, this six-piston caliper integrates advanced Thermlock insulated pistons and stress-flow forged construction to deliver exceptional stopping power with superior thermal management.

Advanced Forged Construction:

Each caliper body is stress-flow forged from premium-grade aluminum alloy billets using computer-generated solid modeling and FEA stress analysis. This forging process re-aligns the metal's internal grain structure to flow within the contour of the caliper body, eliminating the internal stresses that occur in traditional machined billets. The result is an incredibly strong yet lightweight caliper weighing just 4.9 pounds.

Key Features:

• Six-Piston Differential Bore Design: Unique piston configuration provides balanced pad loading for even wear in sustained high-heat environments
• Thermlock Pistons: Exclusive multi-part piston design creates a thermal barrier that reduces heat transfer from pads to caliper body, seals, and brake fluid
• SRS Bridge Plates: Spring-loaded stainless steel plates eliminate bridge wear from pad gouging, prevent pad rattle, and dampen vibrations that cause pad squeal
• Two-Piece Bleed Screws: Positioned on each caliper end with internal fluid crossovers to prevent damage from track debris
• High-Temperature Seals: Square-faced bore seals provide maximum sealing area and controlled piston retraction
• Lightweight Design: Starting weight of 4.9 pounds without sacrificing strength or durability

Performance Benefits:

The Thermlock piston technology significantly reduces operating temperatures, extending component service life and minimizing heat-induced brake fade. The stress-flow forged body provides exceptional rigidity under extreme braking loads while maintaining a compact, lightweight profile. Compatible with the full range of Wilwood pad compounds to match specific brake response and heat requirements for any competition or high-performance driving application.

Ideal for road racing, road course, autocross, and other demanding motorsports applications where consistent, fade-free braking performance is critical.
