The Radi-CAL design is a major departure from traditional symmetric calipers; its asymmetrical shape is computationally optimized to be stiffer and lighter while improving airflow. This results in significantly less caliper \"flex\" under high pressure, providing the driver with more precise modulation and a firmer pedal.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"3\"\u003eAdvanced Thermal Management\u003c\/h3\u003e\n\u003cp data-path-to-node=\"4\"\u003eThe kit utilizes \u003cb data-path-to-node=\"4\" data-index-in-node=\"17\"\u003e380mm x 28mm AP Racing J-Hook rotors\u003c\/b\u003e. These heavy-duty racing discs feature a high vane count for rapid heat dissipation and the proprietary J-Hook groove pattern, which provides a clean pad surface and better \"bite\" without the cracking risks associated with traditional drilled rotors. The floating mounting system allows the disc to expand and contract freely under extreme heat, preventing coning and vibration.\u003c\/p\u003e\n\u003ch3 data-path-to-node=\"5\"\u003eKey Performance Features\u003c\/h3\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e\u003cb data-path-to-node=\"6,0,0\" data-index-in-node=\"0\"\u003eRadi-CAL Design:\u003c\/b\u003e Asymmetrical caliper body increases stiffness and reduces weight for better unsprung mass.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e\u003cb data-path-to-node=\"6,1,0\" data-index-in-node=\"0\"\u003eJ-Hook Racing Rotors:\u003c\/b\u003e 380mm discs provide massive thermal capacity and superior pad outgassing.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003e\u003cb data-path-to-node=\"6,2,0\" data-index-in-node=\"0\"\u003eVentilated Stainless Steel Pistons:\u003c\/b\u003e Reduces heat transfer from the pads to the brake fluid, preventing pedal fade during long stints.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003e\u003cb data-path-to-node=\"6,3,0\" data-index-in-node=\"0\"\u003eFully Rebuildable:\u003c\/b\u003e Calipers feature high-temperature seals and are designed for easy servicing in a racing environment.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,4,0\"\u003e\u003cb data-path-to-node=\"6,4,0\" data-index-in-node=\"0\"\u003eWeight Reduction:\u003c\/b\u003e Significant weight savings over OEM components, improving suspension response and overall agility.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"AP RACING","offers":[{"title":"Standard","offer_id":43099770060861,"sku":"13.01.10218-STD","price":6199.0,"currency_code":"USD","in_stock":true},{"title":"Ferodo DS2500","offer_id":43099770093629,"sku":"13.01.10218-DS2500","price":6399.0,"currency_code":"USD","in_stock":true},{"title":"Ferodo DS1.11","offer_id":43099770126397,"sku":"13.01.10218-DS1.11","price":6399.0,"currency_code":"USD","in_stock":true},{"title":"Ferodo DSUNO","offer_id":43099770159165,"sku":"13.01.10218-DSUNO","price":6399.0,"currency_code":"USD","in_stock":true},{"title":"Ferodo DS3.12","offer_id":43099770191933,"sku":"13.01.10218-DS3.12","price":6399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0898\/5024\/files\/22-es_-_web_listing_cp9449_-_26.png?v=1775931666","url":"https:\/\/www.euromotiv.com\/products\/ap-racing-by-essex-radi-cal-competition-brake-kit-rear-cp9449-380mm-porsche-991-2-gt3-cup","provider":"Euromotiv","version":"1.0","type":"link"}
