Competition Clutch 2002-2008 Acura RSX Stage 2 - Steelback Brass Plus Clutch Kit
The Competition Clutch 8037-2100 is a Stage 2 Street Series clutch kit for the six-speed K20 cars: the 2002-2006 Acura RSX Type-S and, per Competition Clutch, the 2006-2011 Honda Civic Si 2.0L. It is the kit for an owner whose factory clutch has started slipping at the top of second and third after an intake, header and tune, or who simply wants a stronger disc before the stock one wears out, without giving up a pedal and engagement that work in daily traffic.
The K20 in these cars makes its power high in the rev range, and the six-speed gearbox keeps it there, so the clutch sees fast, high-rpm engagements on every aggressive shift. Release is hydraulic: the master cylinder feeds a slave cylinder that pushes the fork and throwout bearing into the pressure plate fingers. The 8037-2100 pairs a Competition Clutch performance pressure plate with a high-torque sprung disc. The sprung hub keeps engagement smooth, which matters on a front-drive car where a harsh clutch shows up as wheel hop and axle shock. Competition Clutch lists the Stage 2 Street Series at up to 80 percent more torque capacity than stock, while the product description for this exact kit quotes a 40-50 percent increase with a slightly firmer pedal. We show both figures so you can judge it for your build.
Check the hydraulics first. A sticky slave cylinder or a weak master can leave the clutch partly engaged or make shifting hard, and the fix is a cylinder, not a clutch kit. If the pedal and fluid are fine and a fourth-gear roll-on from about 3,000 rpm shows rpm running ahead of speed, the disc is slipping. Our clutch slipping guide covers the test, and clutch won't disengage covers the hydraulic side. For bearing noise, see throwout bearing noise.
For a step-by-step road test that separates true slip from other drivetrain faults, read how to diagnose slipping.
Competition Clutch lists the 8037-2100 for the 2002-2006 Acura RSX 2.0L six-speed, which is the Type-S, and the 2006-2011 Civic Si 2.0L six-speed. Our listing carries a 2002-2008 range, but the RSX was sold in the US through the 2006 model year. Five-speed base RSX cars use the 8036 kit family and a different flywheel, so check whether your gearbox is a five- or six-speed before ordering. Engine and gearbox swaps are common in K-series cars; send us your year and VIN, or the engine code, and we will confirm before it ships. More RSX clutch parts are in the rebuild kits and clutch category.
Per the Competition Clutch specification table: pressure plate, single disc, throwout bearing, pilot bushing and alignment tool. The spec table lists the disc as full-face organic, while the series description calls it Brass Plus with alloy backing; either way it is a single sprung disc. No flywheel is included.
