Same high-clamp cover as the 08951, but the cerametallic disc is roughly half stock thickness, which cuts input-shaft inertia enough that the K-series synchros stop fighting fast shifts. Exedy recommends the thin disc for circuit use, and that's how to buy it: a race clutch for an RSX-S or Si that lives at the track. For the street version, look at 08951 or 08951P4.\u003c\/p\u003e\n\u003ch3\u003eWhat It Is and Why It Works\u003c\/h3\u003e\n\u003cp\u003eShift speed on a K-series is limited by how quickly the synchro can match the input shaft to the next gear, and that depends on how much the clutch disc weighs. The thin disc drops that mass hard. Shifts get faster, synchro wear goes down, and the clutch releases cleaner at high rpm. What you give up is heat capacity: less material on the pucks means it glazes sooner if it gets slipped in traffic.\u003c\/p\u003e\n\u003cp\u003eThe cover is ductile iron with about 40 percent more clamp than the Honda plate, and the disc keeps a sprung hub so the gearset isn't eating raw shock. It's the same 215mm, 24-spline family as the rest of Exedy's K-series Stage 2 line.\u003c\/p\u003e\n\u003ch3\u003eSpecs\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e08905\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDisc\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e215mm cerametallic thin disc, sprung hub\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSpline\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e24 tooth x 26mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCover\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDuctile iron, approx. 40 percent over OE clamp (per Exedy)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFlywheel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNot included; needs the 215mm RSX-S \/ 06-11 Si flywheel or Exedy HF02\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIncluded\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePressure plate, disc, release bearing, pilot bushing, alignment tool\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCertification\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eSFI 1.1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIntended use\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCircuit \/ track (per Exedy)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eFitment\u003c\/h3\u003e\n\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVehicle\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eEngine\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2002-2006 Acura RSX Type-S\u003c\/td\u003e\n\u003ctd\u003eK20A2, K20Z1, 6-speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2006-2011 Honda Civic Si\u003c\/td\u003e\n\u003ctd\u003eK20Z3, 6-speed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2002-2005 Honda Civic Si, 2004-2008 Acura TSX\u003c\/td\u003e\n\u003ctd\u003eK20A3, K24A2, with the 215mm flywheel or Exedy HF02\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003ch3\u003eWhat to Know Before You Buy\u003c\/h3\u003e\n\u003cp\u003eFlywheel surface has to be fresh.
