Wilwood 120-13235 Superlite Forged Brake Caliper - FSL6R 6-Piston

The Wilwood 120-13235 FSL6R Superlite 6-piston brake caliper represents the pinnacle of performance braking technology for asphalt short track, late model, modified, and open wheel racing applications. This forged aluminum caliper also excels in road racing, rally, and high-performance sport driving environments where maximum stopping power and minimum weight are critical.

Advanced Internal Fluid Porting Design:

The FSL6R series features a revolutionary redesign with internal fluid ports that completely eliminate the external fluid cross-over tubes found on earlier models. Instead of transfer tubes, the caliper incorporates two additional bleed screw assemblies, allowing differential bore models to be configured for left-hand or right-hand orientation without requiring specific leading or trailing configurations. This streamlined design reduces potential leak points and simplifies installation.

Engineered for Strength and Light Weight:

At just 4.4 pounds assembled weight, the FSL6R achieves an exceptional strength-to-weight ratio through computer-generated solid modeling and advanced stress analysis technology. The caliper body features closed-end bridges with radial transitions to the main body and piston bore housings, eliminating machined steps and sharp shoulders in critical stress areas. This design provides measurably increased overall body strength and superior resistance to deflection under extreme braking loads.

Premium Construction:

• Stress-flow forged from premium grade aluminum alloy billet for maximum durability
• Six-piston configuration delivers exceptional clamping force and pad wear characteristics
• Internal fluid passages eliminate external crossover lines
• Multiple bleed screw locations for simplified bleeding and left/right hand mounting flexibility
• Optimized body geometry resists flex and maintains pad-to-rotor parallelism
• Competition-proven design trusted by professional racing teams

This caliper is designed for serious competition and high-performance applications where reliability, weight savings, and maximum braking performance are non-negotiable requirements.
