Power handling is well in excess of 1000hp. In fact, it has been tested in drag cars with over 1200hp with no slip apparent. However, due to the multi-plate design, it is still surprisingly drivable for street applications, retaining the same clamping force as the R3C design.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan class=\"txmain\"\u003e\u003cspan\u003eLike the R3C it uses a lightweight chrome-moly flywheel, gold-anodised billet aluminium clutch cover and the necessary bearing\/carrier set or pull-push converter kit as required.\u003c\/span\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003ePower handling capacity varies according to the specific model. As a general guide A-size clutches are recommended for up to 450hp, B-size for up to 550hp and C-size for up to 650hp, however power handling will vary up or down depending on the torque characteristics of your engine. Please contact us to check if these clutches will suit your application.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIn the OS lineup (TS, TR, R) have the release sleeve assy \/move alt kit sold separately. In most cases, an OS release sleeve is necessary for use with an OS clutch. The bearing face is tapered to provide maximum surface contact with the clutch fingers, for less pedal pressure. In some cases, the OEM throwout bearing can be used, but typically this results in the pedal pressure becoming very high.\u003c\/span\u003e\u003c\/p\u003e","brand":"OS Giken","offers":[{"title":"R32 GTR Pre-May 1993","offer_id":44339637813435,"sku":"OS Giken-AQPCH012-1","price":4048.0,"currency_code":"CAD","in_stock":true},{"title":"R33 GTR and R32 GTR Post-May 1993 (+$400.00)","offer_id":44339637846203,"sku":"OS Giken-AQPCH012-2","price":4616.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0629\/9556\/2683\/products\/Clutch_Chart_OS_84e912b5-f274-4dc0-a854-7cd66647cdf9.jpg?v=1675344587","url":"https:\/\/drifthq.com\/en-ca\/products\/os-giken-r4c-aluminum-cover-quad-plate-w-center-hub-bnr32-bcnr33-aqpch012","provider":"Drift HQ","version":"1.0","type":"link"}
