It fits directly onto stock single disc flywheels or compatible aftermarket flywheels designed for OE-style clutch kits. No major modifications are required, but proper break-in procedures are essential to ensure clutch longevity and optimal performance. While the clutch works with factory hydraulic systems, upgrading to Clutch Masters’ internal hydraulic release bearing and master cylinder is recommended for best results. Tuning your engine management may be necessary to accommodate the increased torque capacity and maintain drivability.\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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVerify Compatibility:\u003c\/strong\u003e Confirm fitment for your specific year and trim level\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":47131503722671,"sku":"15915-HDTZ","price":935.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/3598\/4815\/files\/M198793103.jpg?v=1782934969","url":"https:\/\/subimods.com\/products\/clutch-masters-fx300-single-disc-clutch-kits-2018-2021-wrx","provider":"Subimods.com","version":"1.0","type":"link"}
