Competition Clutch 06-11 WRX Stage 2-Steelback Brass Plus Clutch Kit (Includes Steel Flywheel)
Competition Clutch 15026-2100 is a complete Stage 2 clutch package for the 2006-2011 Subaru Impreza WRX with the 2.5-liter turbocharged EJ255 and five-speed manual. It is the kit for a WRX on a stage 1 or stage 2 tune that has started to slip in third and fourth as boost comes in, or for an owner whose original clutch is worn and who wants more holding power without giving up a normal street pedal. Everything that wears is replaced at once, including the flywheel.
The 2100 series is Competition Clutch's street-performance level. The kit pairs a performance pressure plate with a high-torque sprung disc whose Brass Plus facings are riveted to a steel backing so the disc resists bursting at high rpm. The sprung hub absorbs driveline shock, which matters on a car that lives in traffic, and the full-face friction gives a smoother take-up than a puck disc. Competition Clutch rates the 2100 kits at roughly 80 percent more torque capacity than stock and aims them at aggressive street driving and moderate track use. The package also includes a forged 4140 steel flywheel, the applicable bearings and an alignment tool, so you are not machining a tired factory flywheel or chasing parts.
Do a low-rpm, full-throttle pull in fourth and watch the tach as boost builds; a flare means the disc is slipping. Before blaming the disc, check the clutch fluid level and condition and look for a leaking slave, because a release system that does not fully return can mimic slip, and one that does not fully release causes drag and grinding. Oil on the bottom of the bellhousing points to a rear main or separator plate leak that has to be fixed during the swap or it will soak the new disc. For budgeting, our automatic vs manual repair cost guide covers typical clutch labor.
Our listing covers the 2006-2011 Subaru WRX (non-STI) with the EJ255 and five-speed. Catalogs for the 15026-2100 also list the 2005-2009 Legacy GT and 2006-2008 Forester XT five-speeds, which share the engine and clutch layout, and some extend the WRX range past 2011. The 2010-up Legacy GT and the WRX STI six-speed are different cars and should be confirmed with us first. Send your year and VIN, or the part number from your current pressure plate, if your car has been modified. Already running a 2100 kit and only need wear parts? The Stage 2 rebuild kit keeps your flywheel, and the Stage 2 replacement disc is sold on its own. For more grip on a bigger turbo, see the Stage 3 segmented ceramic kit.
Our rebuild kits category lists the rest of the 15026 family if you want to compare stages.

Competition Clutch rates the 2100 series at about 80 percent more torque capacity than the stock clutch. It does not publish a single horsepower figure, so for big-turbo builds look at the Stage 3 or Stage 4 kits.
Yes. This 15026-2100 kit includes a 4140 steel flywheel along with the pressure plate, disc, bearings and alignment tool. The RK-2100 rebuild kit is the version without a flywheel.
No. The STI uses a six-speed and a different clutch. This kit is for the 2.5L turbo five-speed WRX; the Legacy GT and Forester XT five-speeds appear in some catalogs, so send your VIN to confirm.
Competition Clutch's 15026 instructions call for 500 to 700 miles of normal driving with no launches or hard, high-rpm engagements before the clutch sees full power.
