Overview

The PRL Motorsports 4-Piston Brake Caliper Kit centers on intelligent standardization: engineered specifically around widely available 312x25mm OEM Civic Si brake rotors, avoiding the high cost and hassle of proprietary two-piece replacement discs.

The caliper body accepts standard FK8 Civic Type-R front brake pad shapes, giving owners instant access to hundreds of street and race compounds. Each caliper is hard-anodized for thermal endurance, chemical resistance, and long-lasting aesthetics.
