Competition Clutch 02-05 Subaru WRX Stage 2 - Steelback Brass Plus Clutch Kit
The Competition Clutch 15029-2100 is a Stage 2 clutch kit for the 2002-2005 Subaru Impreza WRX with the 2.0L turbo and five-speed. It suits the owner whose WRX has a tune, an exhaust or an intercooler and now lets the revs flare in the upper gears when boost hits, but who still drives the car every day and does not want a heavy pedal or a clutch that grabs like a switch. It is a step above a stock replacement while staying friendly in traffic.
The first-generation WRX uses a pull-type clutch. Its release bearing snaps into the center of the pressure plate and pulls the diaphragm back toward the transmission, which is the opposite of the push-type layout Subaru adopted later. This kit is built for that pull-style design. It comes with a performance pressure plate, a single full-face organic disc, a throwout bearing, a pilot bushing and an alignment tool.
A full-face organic disc engages progressively, so slipping the clutch in a parking lot or on a hill feels close to stock. The firmer pressure plate is what adds the holding power. Competition Clutch's product text puts the gain at 40 to 50 percent over stock with a slightly firmer pedal, while its general Stage 2 description claims up to 80 percent and names a Brass Plus facing; its specification table for this part number lists an organic full-face disc. Treat the lower figure as the safe number when you match the kit to your power level.
On a warm engine, select fourth at low rpm and go to full throttle. If the tach jumps as boost builds but the car does not pull harder, the clutch is slipping. A boost leak or timing being pulled makes the car feel slow without that sudden rpm flare, so log boost on the same pull. Grinding into gears or a pedal that sinks points to the hydraulics rather than the disc. Our slipping diagnosis guide explains the full-throttle test step by step, and our repair cost guide helps you budget the job.
Our listing covers the 2002-2005 Subaru WRX. Competition Clutch also lists 15029-2100 for the 2004-2005 Forester, the 1991-1994 Legacy and the 2004-2006 Baja, all in pull-style form. It does not fit the 2006-and-later WRX, which uses a push-type clutch, or the six-speed STI. Subaru used more than one clutch type across these model lines, so compare the release fork and the old pressure plate with the kit, or send us your year and VIN to check. The specification table says no flywheel is included. Browse more WRX clutch parts in the rebuild kits category.

No. The specification table lists the pressure plate, disc, throwout bearing, pilot bushing and alignment tool, with no flywheel. Resurface your flywheel or pair the kit with the 2-671-ST steel flywheel.
Yes. It uses a full-face organic disc, so engagement stays smooth. The pedal is slightly firmer than stock. It is aimed at moderately modified cars rather than big-turbo builds.
Competition Clutch's product text for this kit gives a 40 to 50 percent gain over stock, while its general Stage 2 description says up to 80 percent. Use the lower figure when choosing for your power level.
The kit covers the bearing and pilot bushing. Resurface or replace the flywheel, check the rear main seal and transmission input seal for leaks, and bleed the hydraulics with fresh brake fluid.
