The Wilwood Forged Superlite 4R caliper for right- or high-side mounting features a 1.88/1.75-inch piston arrangement and is intended for 1.25-inch disc applications. The FSL4R redesign uses internal fluid ports to eliminate external crossover tubing and offers adaptable mounting for symmetrical piston models in leading or trailing positions, while differential-bore models retain dedicated left and right orientation for correct installation.
