The kit fits directly to the stock single disc flywheel or compatible aftermarket OE-style flywheels and works with factory hydraulic systems, though upgrading to Clutch Masters’ internal hydraulic release bearing and master cylinder is advised for optimal performance. Due to the aggressive engagement and heavy pedal pressure, this clutch is intended for race use only and is not suitable for daily driving. Proper tuning and setup are essential to maximize the clutch’s capabilities and longevity.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfessional Installation:\u003c\/strong\u003e Recommended\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eModifications Required:\u003c\/strong\u003e None for fitment; hydraulic upgrades recommended\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVerify Compatibility:\u003c\/strong\u003e Confirm fitment for your specific WRX model year and transmission\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eShop with confidence at Subimods—your Subaru parts specialists.\u003c\/p\u003e","brand":"Clutch Masters","offers":[{"title":"Default Title","offer_id":47131503526063,"sku":"15915-HDB6","price":786.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/3598\/4815\/files\/M198793107.jpg?v=1782934966","url":"https:\/\/subimods.com\/products\/clutch-masters-fx500-6-puck-single-disc-clutch-kits-2018-2021-wrx","provider":"Subimods.com","version":"1.0","type":"link"}
