The Wilwood Forged Superlite 4R caliper with 1.25/1.25-inch pistons is specified for 0.81-inch disc applications and benefits from the FSL4R redesign. Internal fluid ports remove the need for external crossover tubing while the caliper's construction and profile provide improved packaging and serviceability in road-race, rally and short-track contexts where precise brake feel and reliable pad wear are required.
