This makes RP-X™ an excellent choice for sprint racing or hill climb events, where full brake performance is essential without requiring any ‘warming up’, but also makes RP-X™ well suited to any type of circuit use where a high initial bite and powerful brake response is desirable.\u003c\/p\u003e\n\n\u003cp\u003eEBC Racing would like to emphasise that it is not a case of RP-X™ being ‘better’ than RP-1™, rather it is ‘different’ and designed to provide a distinctly different response characteristic (more aggressive bite) which some drivers may prefer. For a detailed comparison between the 2 materials, please read the following article where we aim to help you make an informed choice on which material is likely to work best for your application and individual driving style.\u003c\/p\u003e\n\n\u003cp\u003eDoes This Brake Pad Fit Your Needs?\u003cbr\u003e\nThe EBC RP‑X compound is a full race‑grade track pad that’s tuned for maximum stopping power and strong initial bite, with a high and stable friction coefficient (~0.55 μ) across cold to very high temperatures (~0–850 °C). That means 100% brake effectiveness right off cold and sustained performance deep into hard sessions - ideal for sprint racing, time attack, and marquee track days.\u003c\/p\u003e\n\n\u003cp\u003eCompared with the smoother‑feel RP‑1, RP‑X gives you more aggressive bite and higher overall brake torque, accelerating retardation with less pedal travel. This makes it a great fit for heavier cars, high‑powered builds, and cars with under‑servoed brake systems that benefit from extra authority at the caliper.\u003c\/p\u003e\n\n\u003cp\u003eBecause of its high friction and race focus, expect higher rotor wear and more dust versus milder track compounds - a common trade‑off when chasing peak performance.\u003c\/p\u003e\n\n\u003cp\u003eWho This Pad Is For\u003cbr\u003e\n- Drivers who want maximum bite and braking torque on track\u003cbr\u003e\n- Sprint racers, hill climb competitors, and aggressive HPDE drivers\u003cbr\u003e\n- Cars with heavy weight, big power, or under‑servoed braking systems\u003c\/p\u003e\n\n\u003cp\u003eWho Might Prefer Something Else\u003cbr\u003e\n- Drivers focused more on modulation and rotor life than outright stopping power - in those cases, RP‑1’s more progressive feel may be a better match.\u003c\/p\u003e","brand":"EBC","offers":[{"title":"Default Title","offer_id":48175229206778,"sku":"EBCDP82206RPX","price":441.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0325\/6352\/7739\/files\/ffa7cda688bfaafe4466c9b10c3eb901_6389fcd7-8494-4da6-a030-bda5f170ba62.png?v=1767246967","url":"https:\/\/lgcracing.com\/products\/ebc-racing-13-15-porsche-911-991-cast-iron-rotor-only-3-8l-gt3-rp-x-front-brake-pads","provider":"Legacy Racing","version":"1.0","type":"link"}
