Wilwood Forged Superlite 4 (FSLI4) Brake Caliper

Experience superior braking performance with the Wilwood Forged Superlite 4 (FSLI4) brake caliper. Engineered for demanding applications, this caliper utilizes differential bore pistons to actively compensate for mechanical loading and temperature variances across the brake pad.

Key Features:

  • Forged aluminum body for strength and reduced weight.
  • Differential bore pistons (1.88in and 1.75in) for optimized pad wear.
  • Designed for 1.25in disc applications.
  • Ideal for dirt and asphalt oval racing, off-road, rally, and road course use.
  • Provides excellent stopping power and heat management.

The FSLI4 caliper is a top choice for drivers who push their vehicles to the limit. Whether you're competing on the track or tackling challenging terrains, these calipers deliver the reliability and performance you need. Enhance your vehicle's braking system with this high-performance component from Wilwood, available at GGCRACING.
