The Wilwood Forged Superlite 4R caliper, equipped with 1.25/1.25-inch pistons for use with 1.25-inch discs, offers the FSL4R series' internal fluid-port design that eliminates external crossover tubes. The caliper's forged construction and updated body profile improve wheel clearance and integration, providing a compact option for high-demand braking applications across road and short-track environments without implying specific fitment beyond the stated piston and disc dimensions.
