Designed for Honda OEM-spec 312mm rotors and Type R/Type S-spec pads. Verify wheel clearance with the printable template before ordering — caliper dimensions exceed stock. Stainless steel braided brake lines are included and required, not optional. A 355mm rotor variant needs a different bracket, not compatible with this kit as-is.

_______

The Si and A-Spec Integra ship with a single-piston floating caliper that's fine under light use but fades fast once heat builds or pedal pressure climbs — PRL's fixed 4-piston kit fixes that directly with a forged 6061-T6 aluminum body, better pad contact, and real thermal stability.

The design leans on smart standardization rather than proprietary parts: it uses the widely available 312x25mm rotor size already common across 10th/11th Gen Civic Si applications, so replacement rotors stay cheap and easy to source. Pad compatibility matches the FK8 Type R's proven FMSI D1001 pad shape, so you're not stuck hunting for a rare pad profile either. The kit bolts directly to the stock hub and knuckle with no modifications.
