Clutch Masters 2015 Subaru WRX 2.0L 6-Spd 725 Series Race Twin Disc Clutch Kit w/ Aluminum Flywheel
A 2015 WRX with a bigger turbo, an E85 flex-fuel tune or a front-mount and full exhaust will often find the factory clutch first, usually as rpm flaring in third or fourth gear right as boost peaks. Clutch Masters 15020-TD7R-A is the full-race answer for the 2.0 liter direct-injected FA20 WRX with the six-speed manual: an FX725 twin disc with two rigid ceramic discs, a billet aluminum cover and a billet aluminum flywheel, sold as one matched assembly.
The 2015 WRX moved to the FA20 engine and a six-speed TY75 manual, a gearbox with a fairly compact bellhousing. Clutch Masters builds the FX725 for exactly that kind of package: two 7.25 inch (184 mm) friction discs stacked with a floater plate, so the clutch gets far more friction area than one larger disc could fit, while rotating mass stays low and the engine revs quickly between shifts.
TD7R is the Race stage. Both discs are rigid ceramic, with no hub springs, which gives the most grip and the least slip at launch. The cover is machined from billet aluminum and Type 3 hard anodized; Clutch Masters rates its flex at about 0.003 in against as much as 0.030 in for cast or stamped covers, so the release travel your pedal makes goes into the clutch, not into bending the cover. Their QR quick release system uses three spring-loaded bolts so the pressure plate lifts evenly, and the maker says it cuts internal clutch noise by up to half. The A suffix means the kit ships with an aluminum flywheel machined from 6061-T6 billet, built to SFI 1.2 with a replaceable friction insert. Clutch Masters lists the kit at 18 lb shipping weight.
Do a steady full-throttle roll from about 3,000 rpm in fourth gear and watch the tach against the speedometer; slip shows as rpm rising faster than speed. Rule out the hydraulic side first by checking the fluid and bleeding the clutch, since a release problem can feel like a worn clutch. Look under the bellhousing for engine oil, because a leaking rear main will contaminate any new disc. Our slipping diagnosis guide walks through the tests, and the twin disc vs single disc comparison helps you decide whether a race twin is really what your build needs.
Our listing is cataloged for the 2015 Subaru WRX 2.0 liter turbo with the six-speed manual (not the STI, which uses a different 2.5 liter engine and gearbox, and not CVT cars). Clutch Masters' own product page lists 15020-TD7R-A for the 2.0L turbo six-speed WRX under its 2018-and-later application line, and many single-disc WRX clutches split at mid-2018 (VIN J 806877). Because this kit includes its own flywheel, that split matters less, but year and VIN still decide it. The 2022-up WRX uses a 2.4 liter FA24 engine, so do not assume it fits those cars. Send us your year and VIN before ordering and we will confirm. More WRX clutch options, including single-disc 15020 kits, are in our rebuild kits department.
A race clutch puts more shock into the driveline. If you want a smoother street car instead, the ACT HD sprung street kit or the ACT Mod-Twin 225 street twin are gentler options for the same car.

No. It is for the 2.0 liter turbo WRX with the six-speed manual. The STI uses the 2.5 liter EJ engine and a different six-speed, which takes a different clutch.
Clutch Masters lists this part number for the 2.0L turbo six-speed WRX under a 2018-and-later line, and the kit includes its own flywheel. Our listing is cataloged for 2015, so send us your year and VIN and we will confirm before it ships. It is not for the 2.4 liter 2022-up WRX.
TD7R is the Race stage of the FX725 twin disc: two rigid ceramic discs. The TD7S Street and Race version pairs one ceramic disc with one Fiber Tuff organic disc for easier engagement.
Yes. The A suffix kit comes with a billet 6061-T6 aluminum flywheel, SFI 1.2 rated, with a replaceable friction insert.
Clutch Masters says the FX725 is focused on drag racing and is not ideal for the street, although occasional street driving is workable. Expect a sharper engagement, more noise at idle and more driveline vibration than a sprung single disc.
The WRX clutch hydraulics share the brake fluid reservoir type shown on the cap. Bleed the system after install until the clutch releases fully with the pedal on the floor.
