Description

Direct Vehicle Fitment:
- 2017-2021 Honda Civic Si (HC10)
- 2022+ Honda Civic Si (HC11)
- 2018+ Honda Accord
- 2023+ Acura Integra 1.5T (DE4)
- Many other Honda models when using the 312mm Si rotor
- *Will need 20mm spacer to fit OE Honda/Acura wheels

Overview:
- The design philosophy behind our 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.
- PRL's 4-Piston Brake Caliper Kit is a purpose-built solution for drivers who demand more. Engineered in-house, this fixed caliper design improves pad contact, pedal feel, thermal stability, and overall stopping confidence - without compromising street drivability.
- This bolt-on kit is designed and engineered to work directly with your OEM 312mm rotor and integrates cleanly with the stock hub and knuckle setup. The kit also includes steel braided brake lines, offering you better pedal feel and improved confidence when braking harder at higher speeds. A future larger rotor variant is under consideration, but this initial release focuses on fit, performance, and reliability right out of the box.

Quick Specs:
- Caliper Material and Construction: Forged 6061-T6 aluminum, 2-piece body
- Piston Design: 44mm primary / 41mm secondary
- Aluminum 6061-T6 Billet with vented Type 3 hard anodized pistons
- Bracket Material: CNC-machined 4140 billet steel with electrocoated finish
- Pad Compatibility: FMSI D1001 (F50 / Type R / STI pad shape)
- Rotor Fitment: OEM 312mm x 25mm rotor (10th & 11th Gen Civic Si, 2023+ Integra DE4)
- Weight (per side): Approx. 8.8 lbs with bracket and hardware
- Finish: Hard anodized caliper body for thermal resistance, corrosion protection, and clean aesthetics
- Brake Lines: Kit includes a set of stainless steel braided brake lines (required, not optional)

Fitment Notes:
- Compared to the factory floating caliper, the PRL caliper increases outward width by approximately 25mm and vertical height by 30mm on both top and bottom - a total increase of 60mm in overall height. These changes provide greater thermal mass and improved pad contact geometry but may affect clearance on some wheels.
- To help with this we are providing a digital PDF template that can be printed out and used to test the fitment and spacing of the brake caliper kit on your wheels. (make sure to print in a 1:1 ratio and use tape measure to ensure printed template matches actual distances)
