The calipers are paired with substantial 372mm x 34mm, 72-vane J Hook racing discs.\n\nThe Radi-CAL design, a patented asymmetrical caliper, offers a massive increase in stiffness and a reduction in mass compared to conventional calipers. This results in superior pedal feel, modulation, more even pad wear, and extended caliper service life. The Pro5000R calipers utilize forged construction, making this advanced technology accessible to a wider range of enthusiasts. They are engineered with ventilated, domed-back stainless steel pistons to create a thermal barrier, preventing brake fluid fade and maintaining pedal feel under high temperatures. Anti-knockback springs are also integrated into the pistons to mitigate pedal drop during aggressive cornering.\n\nIt is compatible with OEM rear brakes or AP Racing by Essex Competition Rear Brake Kits. The calipers are designed to clear 19\" OEM Competition Style 826M wheels without the need for a spacer. Brake pads are not included, allowing the user to select their preferred compound.\n\nApplication: Track.","brand":"AP Racing","offers":[{"title":"Default Title","offer_id":52686955708728,"sku":"13.01.10175","price":6199.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/661167192.webp?v=1784878885","url":"https:\/\/store.motormia.co\/products\/cp9668-radi-cal-pro5000r-6-piston-caliper-kit-with-372mm","provider":"MOTORMIA","version":"1.0","type":"link"}
