4-Piston Brake Caliper Kit for Honda Civic Si / Acura Integra by PRL Motorsports
The design philosophy behind PRL's new 4-Piston Brake Caliper Kit for the 10th and 11th generation Honda Civic centers on intelligent standardization. By utilizing a widely available 312x25mm rotor size—common across various applications including the 10th and 11th Generation civic Si—we ensure not only optimal braking performance but also maximize ease of maintenance and parts accessibility. This approach eliminates the need for proprietary rotors, helping source replacements more quickly and affordably.
Equally important, the caliper design accommodates the same brake pad profile used in the high-performance FK8 Civic Type R. This strategic decision leverages an existing performance-proven pad format while simplifying logistics for customers. Whether it's for daily driving, spirited weekend use, or track sessions, users benefit from a system engineered with both performance and practicality in mind—delivering OEM-level serviceability without compromise.
The braking system on the Civic Si and Acura Integra was never designed with serious performance driving in mind. The factory single-piston floating caliper gets the job done under light conditions — but once heat builds or pedal pressure increases, it shows its limits fast.
Please Note: *Rotors and Brake Pads do not come with this kit. For separate rotor/pad fitments outside of OEM, please see the install guide below for verification.
