XClutch 15-17 Subaru WRX Base 2.0L Stage 2 Cushioned Ceramic Clutch Kit
The 2015-2017 Subaru WRX launched with the direct-injected 2.0L turbo boxer, rated by Subaru at 268 hp and 258 lb-ft from 2,000 rpm, paired with the car's first six-speed manual. That broad low-rpm torque is exactly what a tune and downpipe multiply, and the factory clutch is usually the first part to give up. XClutch XKSU23015-1C is a Stage 2 single-disc kit for these cars, aimed at owners whose WRX now slips in the higher gears, smells hot after a few pulls, or chatters on launches.
This kit pairs a heavy duty diaphragm pressure plate with a single ceramic disc. XClutch lists a 50 percent clamping force increase over stock and a torque capacity of 520 ft-lb including its safety factor, on a 9-1/16 in disc with a 24-spline, 63/64 in input.
The cushioned disc matters for a street car. A plain sprung ceramic disc grabs hard and can feel on-off at the pedal. XClutch's cushioned version keeps the sprung hub but adds cushioning between the friction surfaces, which lets the clutch take up more progressively. The ceramic friction still gives the heat capacity that organic discs lack once the car makes real power. If you want a sharper bite for motorsport, the sprung ceramic XKSU23015-1B is the same family without the cushion, and the Stage 1 organic XKSU23015-1A suits a lightly modified car.
Rule out the hydraulics first: check the reservoir, bleed the line and make sure the pedal returns fully, since drag or hard shifting from air is not slip. Then log a fourth-gear pull from about 2,500 rpm at full throttle. If engine speed jumps ahead of vehicle speed, the disc is slipping. Our slipping diagnosis guide walks through the test, and the manual transmission repair cost guide covers what a clutch job typically involves.
Our listing covers the 2015-2017 Subaru WRX with the 2.0L turbocharged engine and six-speed manual. It is not for the WRX STI, which uses a different 2.5L engine and six-speed gearbox, or for cars with the CVT. Subaru changed the WRX clutch and flywheel during the 2018 model year, so a 2018 or later car generally needs the earlier 2015-2017 style flywheel to use this kit. Match the part number XKSU23015-1C to what you need, or send us your year and VIN and we will confirm it before it ships. More clutch hardware is in our rebuild kits section.
