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. \u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eEqually 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.
