Competition Clutch 2002-2008 Acura RSX Stage 4 - 6 Pad Rigid Ceramic Clutch Kit
Competition Clutch 8037-0620 is the solid-hub Stage 4 Strip Series kit for the six-speed Acura RSX Type-S and the K20-powered Civic Si. It is built for the car that lives at the drag strip: a turbo or supercharged K20, a K24 swap, or a high-compression build that launches hard on slicks and has already chewed through organic and sprung ceramic discs. If your RSX flares on the 1-2 shift under boost or slips the moment the tires hook, this is the clutch aimed at that job.
The K20 drives a single dry clutch on the flywheel, released by a hydraulic slave cylinder through the fork and throwout bearing. Competition Clutch rates the Stage 4 Strip Series at up to a 250 percent increase in torque capacity over stock, using its performance pressure plate and a six-pad disc with ceramic buttons. The difference on this part number is the hub. Competition Clutch notes that the -0620 discs are solid hub, so there are no torsion springs between the friction pads and the input spline.
A rigid hub saves weight and has nothing to wind up or break when a sticky tire meets a high-rpm launch, which is why drag racers run them. The cost is that every engagement and every bit of engine pulse goes straight into the gearbox, axles and mounts. Expect more gear rattle at idle, harsher takeoffs and more chatter than the sprung version. On a street car that sees traffic, the sprung 8037-1620 holds the same rated torque and is far easier on the transmission.
Make sure the problem really is clutch capacity. Check the master and slave cylinder and bleed the system, since a pedal that does not fully return keeps the plate partly released. Look for oil at the bellhousing from the rear main seal. Then do a controlled pull in a higher gear and watch for the tach jumping ahead of road speed. Our slipping diagnosis guide shows the road test, and shift flare vs. slip helps tell a slow shift from true slip. If the car is stock or only bolt-on, a Stage 2 kit is the better choice.
Our listing title reads 2002-2008 RSX. Competition Clutch lists 8037-0620 for the 2002-2006 Acura RSX 2.0L 6-speed and the 2006-2011 Honda Civic Si 2.0L 6-speed. The RSX was sold in North America for the 2002-2006 model years, so there is no 2007-2008 RSX to fit. The 6-speed RSX is the Type-S; the 5-speed base car uses Competition Clutch's separate 8036 kits, such as the 8036-2400 Stage 1. Swapped cars vary, so confirm the transmission, the flywheel and the input spline, or send us your year and VIN before ordering. More RSX clutch parts are in our rebuild kits collection.

Both are Stage 4 Strip Series kits with a six-pad ceramic disc and the same rated capacity. The -0620 disc has a solid hub with no damper springs, for drag racing; the -1620 has a sprung hub that absorbs shock and suits a street-driven build better.
No. Competition Clutch lists 8037-0620 for the 2002-2006 RSX 2.0L 6-speed (Type-S) and the 2006-2011 Civic Si 2.0L 6-speed. The 5-speed base RSX uses the 8036 series.
No. The kit includes the pressure plate, 6-pad ceramic disc, throwout bearing, pilot bearing or bushing where applicable, and an alignment tool. Resurface your flywheel or buy a steel one separately.
It will work, but expect harsh engagement, chatter in traffic and more gear rattle. It is meant for drag and high-power use; most street cars are happier with a sprung disc.
Competition Clutch recommends shifting as often as possible during the first 500 miles so the disc material beds into the flywheel and pressure plate before hard launches.
