Reusing old, worn seats under a fresh set of upgraded springs is a common mistake that undermines the whole point of the upgrade, since a worn seat can't properly support the new spring's increased seat pressure. Replacing the seats alongside the springs ensures the whole valvetrain package works together as intended. That's the kind of detail that separates genuine engineering from a basic replacement part.\u003c\/p\u003e\n\n\u003ch3\u003eSame Thickness as OEM, No Guesswork\u003c\/h3\u003e\n\u003cp\u003eThese seats match OEM thickness exactly, so there's no need to recalculate installed height or account for a dimensional difference when planning your spring upgrade. That consistency makes these seats a straightforward, drop-in part of a larger valvetrain refresh rather than an extra variable to account for. It's the correct companion part whenever you're stepping up to a genuine performance spring kit. It's a small distinction that makes a real difference once you're actually building the engine.\u003c\/p\u003e\n\n\u003ch3\u003eStraight From Subispeed\u003c\/h3\u003e\n\u003cp\u003eThe correct companion part for a 2002-2014 WRX \/ 2004-2015 STI spring upgrade — don't reuse worn seats under a fresh set of high performance springs.\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\u003e2002-2014\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eWRX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2004-2015\u003c\/td\u003e\n\u003ctd\u003eSubaru\u003c\/td\u003e\n\u003ctd\u003eSTI\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e","brand":"GSC Power Division","offers":[{"title":"Default Title","offer_id":53062354534689,"sku":"GSC1005","price":22.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/files\/d974e774-20cb-483b-94d6-536c90228f0d-800.jpg?v=1784692413","url":"https:\/\/www.subispeed.com\/products\/gsc-p-d-valve-seat-set-oem-replacement-ej205-ej207-ej257","provider":"SubiSpeed","version":"1.0","type":"link"}
