Wilwood FSLI4 Caliper: Differential Piston Performance

The Wilwood FSLI4 caliper is engineered for superior braking performance, particularly in applications demanding sustained high-temperature operation. Its differential bore piston design is crucial for compensating for pad taper wear, ensuring consistent performance across the pad face during intense use.

Advanced FSLI4/ST Technology

This caliper series offers the advantage of differential bore pistons, which optimize pad wear and braking dynamics. For ultimate heat protection, the optional ST (Thermolock) models feature pistons that significantly reduce heat transfer from the pads to the caliper, fluid, and seals, lowering temperatures by up to 25% compared to standard pistons.

• Differential Pistons: Features 1.88-inch and 1.75-inch pistons to manage leading-edge loading and temperature variances, reducing pad taper wear.
• Disc Compatibility: Designed for .81-inch discs, providing a balanced braking system.
• Versatile Application: Ideal for sustained hard braking on dirt and asphalt ovals, as well as off-road, rally, and road course racing.
• Internal Fluid Ports: Eliminates external cross-over tubes for enhanced durability and cleaner aesthetics.
• Dual Bleeders: Equipped with two bleed screw assemblies for efficient brake bleeding.

The Wilwood FSLI4 caliper is the go-to choice for drivers seeking reliable and high-performance braking under extreme conditions. Equip your vehicle with this advanced caliper from GGCRACING.
