Clutch Masters 2015 Subaru WRX 2.0L 6-Spd FX400 8 Puck Clutch Kit
The Clutch Masters 15020-HDCL is the FX400 8-puck kit for the FA20 turbo Subaru WRX 6-speed, listed here for the 2015 model and catalogued by Clutch Masters for 2015-2017. It is built for the owner whose WRX now makes too much torque for an organic, Kevlar or Fiber-Tough disc, but who still drives the car on the street and does not want the hard, chattery engagement of a 6-puck race disc.
The kit uses the same Power Plus I hi-leverage heavy duty pressure plate as the rest of the FX line, matched to a sprung ceramic disc. On the HDCL the ceramic is laid out as a full face of eight segments with a marcel cushion between the linings. Clutch Masters rates the FX400 at 170 percent more holding capacity than stock and calls the 8-puck the less aggressive of its two FX400 layouts: the marcel lets the disc ease in, so engagement is quick but chatter stays minimal. Clutch Masters describes the HDCL as designed for street driven vehicles, which is the reason to pick it over the 6-puck if the car is not a dedicated drag or track build.
Ceramic earns its place on this car through heat resistance. A tuned direct-injected 2.0L turbo loads the clutch hard in the midrange, and repeated pulls or launches cook softer facings. Clutch Masters is clear that ceramic is about holding power and durability, not longer life; driven gently in traffic, any ceramic disc wears faster than a Kevlar one because takeoffs involve more slip.
In the box: pressure plate, 8-puck ceramic disc, release bearing, alignment tool, instruction card and decals, plus a pilot bearing where your application uses one. The flywheel is not included. Shipping weight is about 20 lb.
Pull in fourth from about 2,500 RPM. If engine speed climbs faster than road speed as the turbo comes in, the clutch is slipping; our slipping diagnosis guide walks through it, and flare vs. slip helps if you are not sure what you are feeling. Check for a leaking slave cylinder, old fluid, or rear main seal oil on the bellhousing first. Our clutch chatter guide is worth a read too, since some shudder is expected with any ceramic disc.
Clutch Masters lists 15020-HDCL for the 2015-2017 Subaru WRX 2.0L turbo 6-speed; our listing title is written for 2015. It is not for the WRX STI, the 2.5L 5-speed WRX, or the 2022-up 2.4L car. Subaru changed the WRX clutch during 2018 at VIN J806877, and those later cars use the 15915 series kits. If your car is a 2018, has a swapped gearbox, or already runs an aftermarket flywheel, send us the year and full VIN and we will confirm fitment before it ships.
Comparing options for the same car: the FX400 6-puck 15020-HDC6 bites harder for drag and track use, and the FX350 15020-HDFF is the smoother pick for a tuned street car with occasional track days.

Clutch Masters says the HDCL full face ceramic disc maintains minimal chatter thanks to the marcel cushion and is designed for street driven vehicles. Engagement is still quicker than a Kevlar kit.
Both carry the 170 percent FX400 rating. Pick the 8-puck HDCL for a car that is driven on the street; pick the 6-puck HDC6 for a drag or track car where faster bite matters more than smooth takeoffs.
Yes. Clutch Masters lists this kit for the 2015-2017 WRX 2.0L turbo 6-speed. 2018 cars from VIN J806877 on need the 15915 series.
Not necessarily. Clutch Masters says ceramic is about holding capacity and heat durability, not life expectancy, and easy street driving can shorten its life. It is not recommended for stock or near-stock cars.
No. You get the pressure plate, disc, release bearing, alignment tool, instruction card and a pilot bearing when applicable. Resurface or replace the flywheel during the install.
