The original equipment single piston combination calipers are replaced with a high-efficiency, forged aluminum narrow Superlite four-piston calipers for normal braking, and auxiliary MC4 mechanical calipers for the parking brake. Rotor size is increased from 12.00 in. to 12.88 in., adding brake leverage and cooling capacity, while enriching the look inside your custom wheels and tires. These kits are available with slotted or drilled and slotted rotors with either black or red powdercoated calipers. When brake requirements increase, Wilwood offers their FNSL4R-MC4 rear kits for enhanced performance, increased durability, and high-tech style to complement front brake upgrades.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Disc Brake Kit, Forged Narrow Superlite 4R-MC4 Big Brake Rear Parking Brake, Cross-Drilled\/Slotted Rotors, Four Piston Calipers, Red Powdercoated, Kit<\/p>\n","protected":false},"featured_media":2992,"comment_status":"open","ping_status":"closed","template":"","meta":{"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}}},"product_brand":[],"product_cat":[17],"product_tag":[],"class_list":["post-3179","product","type-product","status-publish","has-post-thumbnail","product_cat-brake-systems","desktop-align-left","tablet-align-left","mobile-align-left","first","instock","shipping-taxable","purchasable","product-type-simple"],"_links":{"self":[{"href":"https:\/\/passionwebs.com\/elite-engines\/wp-json\/wp\/v2\/product\/3179","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/passionwebs.com\/elite-engines\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/passionwebs.com\/elite-engines\/wp-json\/wp\/v2\/types\/product"}],"replies":[{"embeddable":true,"href":"https:\/\/passionwebs.com\/elite-engines\/wp-json\/wp\/v2\/comments?post=3179"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/passionwebs.com\/elite-engines\/wp-json\/wp\/v2\/media\/2992"}],"wp:attachment":[{"href":"https:\/\/passionwebs.com\/elite-engines\/wp-json\/wp\/v2\/media?parent=3179"}],"wp:term":[{"taxonomy":"product_brand","embeddable":true,"href":"https:\/\/passionwebs.com\/elite-engines\/wp-json\/wp\/v2\/product_brand?post=3179"},{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/passionwebs.com\/elite-engines\/wp-json\/wp\/v2\/product_cat?post=3179"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/passionwebs.com\/elite-engines\/wp-json\/wp\/v2\/product_tag?post=3179"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
