This forged aluminum caliper features a four-piston design engineered for responsive braking force, consistent pad engagement, and dependable performance in demanding driving environments. Its lightweight construction helps reduce unsprung mass while maintaining the strength required for high-performance braking systems. The black powder-coated finish provides a clean, durable appearance that complements a wide range of vehicle builds.\u003cbr\u003eThe XRS4R is designed for applications using large-diameter performance rotors and a radial-mount installation configuration. Its four-piston layout helps distribute clamping force across the brake pad for controlled, even contact and predictable pedal response. This makes the caliper well suited to performance street vehicles, track-focused applications, and custom brake upgrades where braking control, weight reduction, and reliable operation are important considerations.\u003cbr\u003eEach Wilwood 120-17205-BK caliper is supplied individually and is intended for use with a compatible rotor, bracket, brake pad, and hydraulic system. Confirm vehicle fitment, mounting requirements, rotor compatibility, and brake system specifications before installation. As a genuine Wilwood component, it offers the quality and application-focused design expected from a leading performance braking manufacturer.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003eForged aluminum construction for strength and reduced unsprung weight\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFour-piston configuration for balanced pad pressure and responsive braking\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eXRS4R caliper design for performance street and track-oriented brake systems\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBlack powder-coated finish for durable protection and a clean appearance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eRadial-mount configuration for compatible high-performance brake applications\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for use with large-diameter performance rotors\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eSold individually\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBrand: Wilwood\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003ePart Number: 120-17205-BK\u003c\/li\u003e\u003c\/ul\u003e","brand":"WILWOOD","offers":[{"title":"Default Title","offer_id":48723104202974,"sku":"WIL120-17205-BK","price":834.16,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0760\/7690\/8766\/files\/WIL120-17205-BK.jpg?v=1787951167","url":"https:\/\/www.racingsupply.ca\/products\/wilwood-120-17205-bk-wilwood-120-17205-bk-xrs4r-4-piston-forged-aluminum-brake-caliper-black","provider":"Racing Supply Co.","version":"1.0","type":"link"}
