Competition Clutch 06-11 WRX / 05-11 LGT Stage 4 - 6 Pad Ceramic Clutch Kit (Inc Steel Flywheel)
The Competition Clutch 15026-1620 is a Stage 4 Strip Series kit for the 2006-2011 Subaru Impreza WRX with the 2.5L turbo EJ255 and five-speed manual. It is aimed at owners whose stock or Stage 2 clutch now flares between gears or lets the revs climb in third and fourth at full boost after a larger turbo, fuel and tune. The maker rates it at up to 250% more torque capacity than the factory clutch, and it arrives with a steel flywheel so you start on a fresh, matched friction surface instead of a worn dual-surface original.
The EJ255 WRX uses a push-type single-disc clutch: the release bearing pushes the diaphragm fingers toward the engine to free the disc. This kit swaps that assembly for a Competition Clutch performance pressure plate clamping a six-pad (six-puck) disc with ceramic buttons. Part number -1620 is the sprung-hub version, so the hub springs still soak up driveline shock; the maker notes that -0620 numbers are the solid-hub race variant. Six small ceramic pads concentrate clamp load on less friction area, which is why it grabs hard and holds far more than an organic disc, and also why it engages more abruptly than any street kit.
Do a third-gear roll-on from about 2,500 rpm with the boost gauge visible; if rpm jumps faster than road speed, the clutch is slipping. Before buying, check the hydraulics: a weak slave cylinder, air in the line or a pedal that does not return fully can keep partial pressure on the fingers and mimic slip. Also rule out an engine-side fluid leak contaminating the old disc, or the new one will fail the same way. If you are weighing a clutch job against other drivetrain repairs, our guide on automatic vs. manual transmission repair cost lays out what the labor typically runs.
This listing is confirmed for the 2006-2011 Subaru WRX 2.5L turbo with the five-speed manual. The title also names the Legacy GT, and the maker's application text covers 2006-2014 WRX and 2005-2009 Legacy GT five-speed, so 2010-2011 Legacy GT owners and 2012-2014 WRX owners should send us the year and VIN before ordering. It does not fit the WRX STI six-speed. Browse more kits in our rebuild kits collection.
If you want a less aggressive pedal for daily driving, compare the Stage 3 segmented ceramic kit or the Stage 2 kit with steel flywheel. A spare clutch alignment tool kit is useful if you service more than one car.

It can be driven on the street, but the six-pad ceramic disc engages quickly and can chatter in first and reverse. If the car is mostly a commuter with moderate power, the Stage 3 segmented ceramic kit is the smoother choice.
Yes. This kit includes a steel flywheel along with the pressure plate, 6-pad ceramic disc, release bearing where applicable, pilot bearing or bushing where applicable, and an alignment tool.
The maker states that -0620 versions use a solid hub. This -1620 kit uses a sprung hub, which keeps some driveline cushioning for a car that still sees street miles.
No. The STI uses a six-speed transmission and a different clutch. This kit is for the 2.5L turbo WRX five-speed. Send your VIN if you are unsure which transmission you have.
Plan on 500-700 miles of normal driving without launches, hard shifts or towing so the friction surfaces seat evenly.
