Description
The Wilwood Forged Superlite Internal 4 Left Brake Caliper (part number 120-11330) is a hydraulic brake caliper configured for the rotor and mounting dimensions listed below. It uses lug mounting with a listed nominal rotor thickness of 1.25 in.
Piston sizing, rotor thickness, and mounting geometry determine how this caliper integrates with the brake system. A matching pad shape identifies the pad interface, while compound selection remains a separate operating-temperature decision.
