That combination is especially popular in controlled race divisions where rules require a stock-appearing rotor, but where the underlying metallurgy and cooling performance still need to hold up to real competition use. It's the same DBA 4000 Series engineering underneath, just without the visual cues. It's the kind of upgrade that quietly does its job without ever needing a second thought.\u003c\/p\u003e\n\n\u003ch3\u003eThe Same Core Technology, Just a Different Finish\u003c\/h3\u003e\n\u003cp\u003eUnderneath that smooth finish, this rotor still uses the same high carbon alloyed iron and Thermal Stability Profiling as the rest of the 4000 Series lineup, so there's no performance compromise for choosing the OE-style look. It's a smart option for anyone racing in a class with rotor appearance restrictions, or simply anyone who prefers a cleaner look through the wheel. Real performance doesn't have to come with an aggressive appearance. That's real, functional engineering, not just a marketing claim.\u003c\/p\u003e\n\n\u003ch3\u003eStraight From Subispeed\u003c\/h3\u003e\n\u003cp\u003eA smart choice for 2003-2012 WRX \/ 2004-2012 STI in a class with rotor appearance restrictions — full 4000 Series performance in an OE-style finish.\u003c\/p\u003e\n\n\u003cp\u003eThis Part Fits:\u003c\/p\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003cth\u003eYear\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2003-2012\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2004-2012\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eSTI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"DBA","offers":[{"title":"Default Title","offer_id":53061590647073,"sku":"DBADBA4655-10","price":202.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/files\/375cc2334f53137f67284527475819c6L.jpg?v=1784688584","url":"https:\/\/www.subispeed.com\/products\/dba-03-13-subaru-wrx-w-sti-calipers-170mm-handbrake-rear-4000-series-plain-rotor","provider":"SubiSpeed","version":"1.0","type":"link"}
