Being a billet cam rather than a re-ground factory core, this camshaft starts from a precision blank rather than being limited by the factory core's base circle and material properties. That billet construction is what lets GSC achieve consistent, repeatable lobe profiles across every cam they produce. It's the kind of upgrade that quietly does its job without ever needing a second thought.\u003c\/p\u003e\n\n\u003ch3\u003eWhat This Cam Actually Feels Like to Drive\u003c\/h3\u003e\n\u003cp\u003eIn terms of real-world feel, this cam delivers maximum top-end power for a car that's built to be driven hard, giving you a clear expectation of how the car will behave before you commit to the install. GSC's cam lineup is specifically staged this way so you can choose the level of aggressiveness that matches your actual build and driving style, rather than guessing at a generic \"stage\" cam from another brand. Pairing this cam with appropriately matched valve springs and retainers is worth planning for at the same time. 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 billet S3 cam for 2004-2007 STI — GSC's most aggressive standard grind for serious builds, with genuine GSC engineering behind the lobe profile.\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\u003e2004-2007\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":53062355812641,"sku":"GSC7025S3","price":999.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0737\/9029\/2257\/files\/b4dbafb1-f94a-48c0-916e-75a2257a9900-800_80e64113-b2a2-4620-a510-e9910402910b.jpg?v=1784692421","url":"https:\/\/www.subispeed.com\/products\/gsc-p-d-subaru-ej255-ej257-usdm-w-intake-avcs-s3-cams-282-282-billet","provider":"SubiSpeed","version":"1.0","type":"link"}
