The Wilwood Forged Superlite Internal (FSLI) series is the latest evolution of the benchmark Superlite caliper, trusted across short track, late model, road racing, and off-road competition. This redesigned model features internal fluid ports that eliminate the need for external crossover tubes, removing the risk of tube damage during aggressive driving or mechanical failure.

Engineered for versatility, the FSLI utilizes a symmetrical piston bore design and four bleed screw assemblies. This allows a single caliper to be mounted in either leading or trailing positions on the left or right side of the vehicle, simplifying spares management for race teams. The forged aluminum body provides superior stiffness under high clamping loads, ensuring consistent pedal feel and brake modulation.
