ACT 2016 Subaru WRX HD/Race Sprung 6 Pad Clutch Kit
A tuned 2016 Subaru WRX makes enough torque to overwhelm the factory clutch quickly, and the usual signs are slip in third and fourth at boost, a burning smell after launches, or an rpm flare on every hard shift. The ACT SB5-HDG6 is built for that owner: a Heavy Duty pressure plate paired with a 6-pad, spring-centered ceramic race disc, rated well above stock for high-horsepower street and race use.
The 2016 WRX uses the 2.0L turbocharged FA20 engine with a six-speed manual. Boost arrives hard in the midrange, and that torque spike is what makes a worn or stock clutch slip. ACT rates the SB5-HDG6 at 535 ft-lb at the crank, 69 percent more than the original clutch. The SB014 Heavy Duty pressure plate raises clamp load, and the 6228218 disc uses six ceramic pads on a sprung hub, which damps driveline vibration while holding much more heat than an organic facing. ACT is clear about the trade-off: engagement is more aggressive, shifts are faster, and friction life is moderate. Pedal effort stays light to moderate.
Log a full pull in fourth gear and compare engine rpm against vehicle speed; a slipping clutch shows rpm rising faster. Check the clutch hydraulics and bleed them if the pedal feels soft, and look for oil at the bellhousing, since a leaking rear main seal will ruin a new disc. Our slipping diagnosis guide covers the checks step by step, and our manual repair cost guide explains why replacing the clutch while the transmission is out is the cost-effective move.
If the car is a daily driver with a mild tune, a ceramic puck disc can feel harsh in traffic. ACT's street version of this kit, the SB5-HDSS with an organic disc, is the smoother choice.
This listing is for the 2016 Subaru WRX 2.0L turbo six-speed (not the STI and not CVT cars). ACT's application chart for SB5-HDG6 is wider: it also lists 2015-2018 WRX, 2006-2014 Impreza WRX 2.5L, 2005-2009 Legacy GT and Outback XT, 2006-2008 Forester XT and the 2006 Saab 9-2X Aero. One warning from ACT: Subaru switched to 240 mm clutch parts in mid-2018 production starting at VIN J806877, and ACT clutches and flywheels do not fit those cars. Send us your year and VIN if you are unsure.

No. It contains the pressure plate, disc, release bearing, pilot bearing and alignment tool. Resurface your flywheel or add ACT's XACT Prolite 600475 or Streetlite 600480.
Not if the VIN is J806877 or later. ACT says Subaru moved to 240 mm clutch parts at that point, and ACT kits and flywheels do not fit those cars.
ACT recommends this kit for high-horsepower street or race use. Engagement is more aggressive than an organic disc, so mildly modified daily drivers usually prefer the SB5-HDSS.
ACT rates it at 535 ft-lb measured at the crank, 69 percent over the factory clutch.
No. The STI uses a different transmission and clutch. ACT's SB5-HDG6 chart covers the WRX, not the STI, for 2015-2018.
