The Wilwood Superlite FNSL4R caliper in a 1.12/1.12 arrangement is paired here with a 1.10 rotor specification. It delivers the compact caliper packaging and piston sizing required for installations that call for the FNSL4R mounting pattern and the 1.10 rotor interface, helping ensure proper pad contact and consistent braking response when integrated into compatible rear brake setups.
