By utilizing a widely available 312x25mm rotor size—common across applications including the 10th and 11th Gen Civic Si—it ensures optimal braking performance while maximizing ease of maintenance and parts accessibility, eliminating the need for proprietary rotors.\u003c\/p\u003e\n\u003cp\u003eThe caliper design accommodates the same brake pad profile used in the high-performance FK8 Civic Type R, leveraging a performance-proven pad format while simplifying logistics. Whether for daily driving, spirited weekend use, or track sessions, the system is engineered for both performance and practicality—delivering OEM-level serviceability without compromise.\u003c\/p\u003e\n\u003cp\u003eThe factory single-piston floating caliper on the Civic Si and Acura Integra was never designed with serious performance driving in mind; once heat builds or pedal pressure increases, it shows its limits fast. PRL's fixed-caliper design improves pad contact, pedal feel, thermal stability, and stopping confidence without compromising street drivability. This bolt-on kit works directly with your OEM 312mm rotor, integrates cleanly with the stock hub and knuckle setup, and includes steel braided brake lines for better pedal feel when braking harder at higher speeds.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCaliper: forged 6061-T6 aluminum, 2-piece body, hard anodized finish\u003c\/li\u003e\n\u003cli\u003ePiston design: 44mm primary \/ 41mm secondary, 6061-T6 billet with vented Type 3 hard anodized pistons\u003c\/li\u003e\n\u003cli\u003eBracket: CNC-machined 4140 billet steel with electrocoated finish\u003c\/li\u003e\n\u003cli\u003ePad compatibility: FMSI D1001 (F50 \/ Type R \/ STI pad shape)\u003c\/li\u003e\n\u003cli\u003eRotor fitment: OEM 312mm x 25mm rotor (10th \u0026amp; 11th Gen Civic Si, 2023+ Integra)\u003c\/li\u003e\n\u003cli\u003eWeight approximately 8.8 lbs per side with bracket and hardware\u003c\/li\u003e\n\u003cli\u003eIncludes required stainless steel braided brake lines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e2017–2021 Honda Civic Si (HC10)\u003c\/li\u003e\n\u003cli\u003e2022+ Honda Civic Si (HC11)\u003c\/li\u003e\n\u003cli\u003e2018+ Honda Accord\u003c\/li\u003e\n\u003cli\u003e2023+ Acura Integra (DE4)\u003c\/li\u003e\n\u003cli\u003eMany other Honda models when using the 312mm Si rotor (requires 20mm spacer to fit OE Honda\/Acura wheels)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e(2) PRL 4-Piston forged aluminum calipers\u003c\/li\u003e\n\u003cli\u003e(2) Stainless steel braided brake lines\u003c\/li\u003e\n\u003cli\u003e(2) Application-specific CNC-machined steel brackets\u003c\/li\u003e\n\u003cli\u003eFull hardware kit: crush washers, banjo bolts, security pins, pad spring bridges, bolts, bleeder caps\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eRotors and brake pads are not included with this kit.\u003c\/em\u003e\u003c\/p\u003e","brand":"PRL Motorsports","offers":[{"title":"Satin Blue","offer_id":49622165454986,"sku":"PRL.PRL.1167.1.BLU","price":1299.0,"currency_code":"USD","in_stock":true},{"title":"Gunmetal Gray","offer_id":49622165487754,"sku":"PRL.PRL.1167.1.GRY","price":1299.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0688\/4599\/4122\/files\/prl-motorsports-4-piston-big-brake-caliper-kit-honda-civic-si-acura-integra-blue-470177.jpg?v=1782866865","url":"https:\/\/www.sbxperformance.com\/products\/prl-motorsports-4-piston-brake-caliper-kit-honda-civic-si-acura-integra","provider":"SBX Performance","version":"1.0","type":"link"}
