Competition Clutch 2002-2008 Acura RSX Stage 4 - 6 Pad Ceramic Clutch Kit
The Competition Clutch 8037-1620 is a Stage 4 Strip Series kit for a K20-powered Acura RSX that makes far more power than the factory clutch can hold: turbo or supercharged builds, K24 swaps, and cars that see drag strip launches. It pairs a Competition Clutch performance pressure plate with a sprung six-puck ceramic disc. If your RSX Type-S or built base car flares the revs on a hard pull, glazed an organic or Stage 2 disc, or burns clutches on launch, this kit is aimed at that problem.
The RSX bolts a single-disc dry clutch to the flywheel of the 2.0L K20 four-cylinder, with a hydraulic slave cylinder pushing the release bearing. A K20 makes peak power near its redline, and forced induction adds a large torque spike in the midrange, so the clutch has to clamp hard without slipping at both ends. Competition Clutch rates its Stage 4 Strip Series at up to a 250 percent increase in torque capacity over stock. Six ceramic buttons bite much harder than a full-face organic disc and tolerate the heat of repeated launches, while the sprung center on this 1620 version still absorbs some driveline shock. The rigid version, 8037-0620, uses a solid hub for pure racing use.
The trade-off is drivability. A six-puck ceramic disc engages quickly with little slip, so smooth takeoffs take practice, chatter in traffic is common and wear on the flywheel face is higher than with an organic disc. This is a build-car clutch, not a fix for a stock commuter.
A slipping clutch and a hydraulic fault can feel alike, so start at the master and slave cylinder: a soft pedal, low fluid or a leak means the clutch may not be fully engaging or releasing. Then do a controlled pull in fourth gear from low rpm and watch whether the tach jumps ahead of road speed. Our slipping diagnosis guide explains the road test, and shift flare vs. slip helps separate true slip from a rev rise during a slow shift. Be honest about power level too: if the car is stock or lightly modified, a Stage 2 kit will be much nicer to live with.
Our listing title reads 2002-2008 RSX. Competition Clutch describes the 8037 Stage 4 kit as fitting the 2002-06 Acura RSX and the 2006-11 Honda Civic Si 2.0L 6-speed. The RSX was only sold in North America through the 2006 model year, so treat the K20 RSX as the fitment and do not assume a 2007-08 car of another model fits. Competition Clutch also builds an 8036 series for 5-speed base cars, so check which transmission your car has, match the old disc spline and pressure plate size, or send us your year and VIN to confirm.

Prefer a solid-hub disc for a dedicated drag car? The 8037-0620 rigid Stage 4 is the same clamp with no hub springs.

Competition Clutch lists the 8037 series for the 2002-06 RSX and 2006-11 Civic Si 2.0L 6-speed, and sells a separate 8036 series for 5-speed cars. Send us your year and VIN, or the transmission code, and we will confirm.
Both are Stage 4 kits with a 6-puck ceramic disc. The 1620 disc has a sprung hub to absorb driveline shock; the 0620 has a solid hub for dedicated racing use.
It will drive, but engagement is very quick and chatter at low speed is normal. Competition Clutch builds it for high-horsepower and drag racing cars. A stock or mildly modified RSX is better served by a Stage 2.
No. The kit includes the pressure plate, disc, throwout bearing, pilot bearing or bushing and alignment tool. Resurface your flywheel or replace it.
Competition Clutch recommends shifting as often as possible during the first 500 miles so the disc material embeds evenly into the pressure plate and flywheel surfaces.
