Competition Clutch 06-11 WRX / 05-11 LGT Stage 3 - Segmented Ceramic Clutch Kit (Inc Steel Flywheel)
Competition Clutch 15026-2600 is the Stage 3 street/strip kit for 2006-2011 Subaru WRX models with the turbocharged 2.5L EJ255 and five-speed gearbox. It suits a tuned WRX with intake, exhaust, downpipe and a stage 2 or larger map that now slips on hard pulls, yet still has to be pleasant in traffic. The maker rates it at up to 150% more torque capacity than stock, and the kit ships with a steel flywheel so the friction disc beds against a fresh surface.
Unlike a puck-style race disc, the Stage 3 disc carries segmented ceramic facings around its full circumference on a high-torque sprung hub. The full ring of friction spreads clamp load over more area, giving strong holding power with a smoother, more progressive take-up than a six-pad design. The performance pressure plate raises clamp load over the factory cover for quick engagement. In the push-type EJ255 setup, the release bearing presses the diaphragm toward the engine to free the disc, so the hydraulic system has to be healthy for the new clutch to release fully.
A fourth-gear pull from low rpm is the quickest test: if the tachometer jumps ahead of road speed, the disc is slipping. Check that the pedal returns all the way and that the slave cylinder is not leaking, since residual pressure on the fingers can cause slip too. Look for oil on the bellhousing from a rear main seal or separator plate; oil on a new ceramic disc ruins it. Our manual vs. automatic repair cost guide helps you budget the labor.
Listed fitment is the 2006-2011 Subaru WRX 2.5L turbo five-speed. The title adds the Legacy GT; the maker's own application note lists 2006-2014 WRX and 2005-2009 Legacy GT five-speed. If you own a 2010-2011 Legacy GT or a 2012-2014 WRX, send your year and VIN so we can confirm before shipping. WRX STI six-speed cars need a different kit. See related parts in the rebuild kits section.
Keep a Stage 3 replacement disc for the next refresh, since the pressure plate and flywheel are often reusable. For a drag-focused build, step up to the Stage 4 6-pad kit.

Stage 3 uses a full ring of segmented ceramic facing, so it takes up more smoothly than the six-pad Stage 4 disc. Stage 4 holds more torque but engages harder and suits strip use.
A performance pressure plate, sprung segmented ceramic disc, steel flywheel, release bearing where applicable, pilot bearing or bushing where applicable, and an alignment tool.
Yes. A Stage 3 replacement disc made for this 15026-2600 kit is listed in our store, so a later refresh can reuse a good pressure plate and flywheel.
The maker's application text includes 2012-2014 WRX, but this listing is confirmed for 2006-2011. Send your VIN and we will check before you order.
Not always. Inspect the slave cylinder for leaks and bleed with fresh brake fluid. Replace parts that leak or let the pedal sit low.
