The FK8 uses a large 350mm front brake disk, with only a 305mm rear rotor. Our kit increases the rear brake disk by 25mm\/ 1 inch to help even out the brake bias. The larger brake rotor disk offers higher lateral strength which increases stopping power. Cross drilled, slotted, or full face blank options are available. This is a great add on to match the new 2020 Fk8 2 piece rotor that now comes standard.\u003c\/p\u003e\n\u003cp\u003e2015-16 Civic Type R FK2 compatible as well per Euro customers confirming the FK2 and FK8 use the same braking hardware.\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"d2edcug0 hpfvmrgz qv66sw1b c1et5uql rrkovp55 jq4qci2q a3bd9o3v knj5qynh oo9gr5id\"\u003eWith the increase of 8.2% in size, there are two most common questions:\u003c\/span\u003e\u003c\/p\u003e\n\u003col class=\"bi6gxh9e aov4n071 fjf4s8hc gg216y78\"\u003e\n\u003cli\u003e\n\u003cdiv class=\"bi6gxh9e\"\u003e\n\u003cspan class=\"d2edcug0 hpfvmrgz qv66sw1b c1et5uql rrkovp55 jq4qci2q a3bd9o3v knj5qynh oo9gr5id\"\u003eIsn't the extra inner space on the rotor surface not being utilized because of the pads being same OE size?  \u003c\/span\u003e\u003cstrong\u003eAnswer: correct, not used...for a reason.\u003c\/strong\u003e\n\u003cdiv class=\"bi6gxh9e\"\u003e\n\u003cspan class=\"d2edcug0 hpfvmrgz qv66sw1b c1et5uql rrkovp55 jq4qci2q a3bd9o3v knj5qynh oo9gr5id\"\u003eYou can see in the picture the caliper and pad assembly moved outward by 12.5 mm.  The pad size did not change, and you don't want to change the pad size - unless you also upgrade the master cylinder and brake booster designed in the FK8.  \u003c\/span\u003e\u003cspan class=\"d2edcug0 hpfvmrgz qv66sw1b c1et5uql rrkovp55 jq4qci2q a3bd9o3v knj5qynh oo9gr5id\"\u003eThe FK8's master cylinder is designed with a set or defined pressure that's multiplied by the brake booster.  I\u003c\/span\u003encreasing the pad size or surface area without upgrading the master cylinder and brake booster, you've effectively reduced your pressure at the pad to rotor contact area...reducing your braking force.\u003c\/div\u003e\n\u003cdiv class=\"bi6gxh9e\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"bi6gxh9e\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"bi6gxh9e\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003eHow does a larger diameter make for more braking force?\u003cspan\u003e \u003c\/span\u003e\u003cstrong\u003eAnswer: no, braking force is increased due to increase in \"lever\" length. \u003cspan\u003e \u003c\/span\u003e\u003c\/strong\u003eImagine you push on a lever that's 1 foot long around a center point or fulcrum. Now lengthen that lever by 50% to 1.5 foot long. The result is more moment of torque. You work less but generate more torque; hence higher degree of brake torque or stopping power.  This means the caliper-piston-pads assembly has to work 8.2% less but generates more torque ala more braking force. \u003cspan data-mce-fragment=\"1\"\u003eBy simply increasing rotor size, you're already increasing braking force without doing anything else.\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cdiv class=\"video-wrapper\"\u003e\u003c\/div\u003e","brand":"Ballade","offers":[{"title":"Default Title","offer_id":47865162170662,"sku":"BS-FK8-RBRJ","price":747.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0790\/2478\/3654\/files\/image_3000x_177235b4-eb0d-41b6-aa7d-18cb906fc88d.webp?v=1710543995","url":"https:\/\/abautoworks.com\/products\/ballade-sports-two-piece-rear-rotor-kit-15-civic-type-r-fk8","provider":"ABAutoworks","version":"1.0","type":"link"}
