By dramatically reducing the rotating mass, this kit helps your flat-six engine rev more freely and deliver more of its power directly to the wheels — ideal for spirited driving or track-toned street builds. It also raises clutch load capacity and thermal resistance to support aggressive driving or high-gearbox stress without compromising daily usability.\u003c\/p\u003e\n\u003ch2 data-start=\"790\" data-end=\"808\"\u003eFitment Notes\u003c\/h2\u003e\n\u003cul data-start=\"809\" data-end=\"1376\"\u003e\n\u003cli data-start=\"809\" data-end=\"994\"\u003e\n\u003cp data-start=\"811\" data-end=\"994\"\u003eCompatible with \u003cstrong data-start=\"827\" data-end=\"887\"\u003ePorsche 718 GT4, Boxster Spyder, and 718 GTS 4.0L\u003c\/strong\u003e models — any 4.0 L manual-transmission 718 platform (2020 onward).\u003cspan class=\"\" data-state=\"closed\"\u003e\u003cspan class=\"ms-1 inline-flex max-w-full items-center relative top-[-0.094rem] animate-[show_150ms_ease-in]\" data-testid=\"webpage-citation-pill\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"995\" data-end=\"1124\"\u003e\n\u003cp data-start=\"997\" data-end=\"1124\"\u003eDesigned as a \u003cstrong data-start=\"1011\" data-end=\"1061\"\u003edirect-replacement for OEM flywheel and clutch\u003c\/strong\u003e — uses factory bell-housing, input shaft, and clutch linkage\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1125\" data-end=\"1250\"\u003e\n\u003cp data-start=\"1127\" data-end=\"1250\"\u003eIntended for manual transmission only — not compatible with PDK\/automatic variants. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003cspan class=\"ms-1 inline-flex max-w-full items-center relative top-[-0.094rem] animate-[show_150ms_ease-in]\" data-testid=\"webpage-citation-pill\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"1251\" data-end=\"1376\"\u003e\n\u003cp data-start=\"1253\" data-end=\"1376\"\u003eInstallation requires full clutch\/flywheel removal;
