Competition Clutch Honda/Acura K Series 184mm Twin Disc Ceramic Clutch Kit
The K20 in the RSX Type-S and Civic Si takes boost and big cams well, but the stock size clutch behind it does not. Turbo K-series owners who have already burned through a puck disc, or who are building for track and drag use, usually end up shopping for a twin disc. Competition Clutch 1848037-2 is that kit: two 184 mm ceramic discs, a floater and a chromoly flywheel in one package for the K-series six speed cars. If your clutch slips at the top of second or third, or a heavy single disc has made the car hard to drive, start here.
Torque capacity comes from friction surface area and clamp load. Rather than making one disc larger, this kit uses two 184 mm (7.25 inch) discs separated by a floater plate, so the friction area roughly doubles while the assembly stays compact and light enough for an engine that lives above 7,000 rpm. Both discs carry segmented ceramic facing on a solid hub under a diaphragm pressure plate. Competition Clutch rates its full race 184 series twin disc kits up to 1,350 hp, and its Power-V drive system lets the floater plates self-center so drive loads spread evenly and the assembly stays balanced. Assemblies are hand built and tested in Anaheim, California.
Included: chromoly flywheel, both discs, floater, pressure plate, throwout bearing, pilot bushing, alignment tool and mounting hardware. For a side by side look at feel and noise, read our twin disc vs single disc comparison.
Make a third gear pull from about 3,000 rpm at full throttle; engine speed jumping ahead of road speed means slip. Before blaming the disc, check that the clutch fully releases and that the hydraulics are healthy; the RSX and Civic Si use a hydraulic slave cylinder, and a soft or sinking pedal is a hydraulic problem, covered in our clutch bleeding walkthrough. Our slip diagnosis guide and flare vs slip explainer help you separate a worn clutch from other faults.
Application listings for 1848037-2 cover the 2002-2006 Acura RSX and the K20 Honda Civic Si. The part number follows Competition Clutch's 8037 family, which is the RSX Type-S six speed and Civic Si clutch; the base RSX with the five speed uses the separate 8036 family. Some catalogs also show the 2006-2011 Civic Si and the 2008 Civic Mugen Si. Because K-series swaps and transmission swaps are everywhere, match your transmission and flywheel bolt pattern before ordering, or send us your year, VIN and swap details so we can check it. Compare our single disc 8037 Stage 4 ceramic kit if your power level does not need a twin, or browse every clutch and rebuild kit.
A twin disc puts more load on worn parts around it. A RSX master, slave and braided line kit firms up release, and fresh engine and transmission mounts cut down the wheel hop and shift slop that a grabby clutch exaggerates.

It is not listed for the TSX. K24 swaps vary by transmission and flywheel, so confirm your exact transmission and flywheel pattern with us first.
Yes. It includes the chromoly flywheel, two 184 mm segmented ceramic discs, the floater, pressure plate, throwout bearing, pilot bushing, alignment tool and hardware.
Some rattle from the floater and discs at idle in neutral is common with race twin disc clutches and is not a defect. It usually goes quiet when the pedal is pressed.
The kit covers the clutch itself. Many K-series owners also renew the master and slave cylinder, the clutch line and worn engine mounts during the same job.
