Clutch Masters 2015 Subaru WRX 2.0L 6-Spd FX300 Clutch Kit
The Clutch Masters 15020-HDTZ is the FX300 single disc clutch kit for the first FA20 turbo Subaru WRX with the 6-speed manual. Our listing is written for the 2015 car, and Clutch Masters lists the same part number for 2015 through 2017. If your WRX has a tune, a bigger intercooler or a turbo-back exhaust and the stock clutch now flares RPM in third and fourth when boost comes in, this is the kit built for that job: more clamp than a stock replacement, but still meant to be driven on the street every day.
The direct-injected 2.0L turbo makes most of its torque low in the rev range, and that is exactly where a tired factory disc gives up. The FX300 pairs the Clutch Masters Power Plus I heavy duty pressure plate with a steel-backed disc faced in segmented Kevlar. Splitting the facing into segments puts the same clamp load on less area, so pressure per square inch goes up and the disc holds more torque. Clutch Masters rates the FX300 at 110 percent more holding capacity than stock and describes it as a street clutch for medium-boost turbo cars, not a track part. The Kevlar is non-abrasive, so it is easy on the flywheel face, and pedal effort is only slightly heavier than the factory clutch.
In the box: the pressure plate, the sprung-hub disc with a marcel spring wafer, a release bearing, an alignment tool, an instruction card and decals. Clutch Masters includes a pilot bearing only where the application calls for one. The flywheel is not included.
Put the car in fourth around 2,500 RPM and go to full throttle on a safe, empty road. If the tach jumps ahead of road speed as the turbo spools, the disc is slipping. Our slipping diagnosis guide walks through this road test, and the clutch slipping causes page covers oil on the disc and hydraulic problems that look like a worn clutch. If the issue is grinding into gear or a clutch that will not release, check the slave cylinder and bleed the hydraulics before buying a kit.
Clutch Masters lists 15020-HDTZ for the 2015-2017 Subaru WRX 2.0L turbo 6-speed. It is not for the WRX STI, which uses the 2.5L and a different gearbox. Subaru changed the WRX clutch in the middle of the 2018 model year at VIN J806877. Cars from that VIN on take the 15915 series kits instead, and an early 2018 car built before that VIN should be confirmed with us before ordering, since the 15020 kits are matched to the 2015-2017 flywheel. Send us the year and full VIN and we will check it before it ships.
If you want a smoother, longer-life kit for a lightly modified car, the FX200 15020-HDKV fits the same cars. For heavier tunes with more boost, step up to the FX350 for this WRX.

Yes. Clutch Masters lists this part number for the 2015-2017 WRX 2.0L turbo 6-speed. Our listing title only names 2015, but the kit is the same for all three years.
Not if the car was built from VIN J806877 on, because Subaru switched to a larger clutch at that point; those cars take the 15915 series. For an early 2018 car before that VIN, send us the full VIN so we can confirm the flywheel before ordering.
Yes. Clutch Masters calls it a street clutch with only slightly heavier pedal effort and long life. It is not recommended for track use.
No. The kit includes the pressure plate, disc, release bearing, alignment tool and instruction card. Resurface your flywheel or replace it during the install.
Clutch Masters requires at least 500 miles of easy driving before hard launches or full-boost pulls. Skipping it shortens disc life.
No. The kit ships with a new release bearing, and reusing a worn one is a common cause of noise right after a clutch job. Install the new bearing and check the fork pivot while you are in there.
