ACT 2013 Scion FR-S HD/Perf Street Sprung Clutch Kit
The ACT SB8-HDSS is a heavy duty street clutch package for the 2.0L FA20 twins: the Scion FR-S, Subaru BRZ and Toyota 86. If your clutch is slipping in third and fourth after a tune or header, chatters on a hill start, or the factory flywheel is scored from a worn-out disc, this kit replaces every wear part at once and adds ACT's lightweight Prolite flywheel in the same box.
The FA20 bolts to a 6-speed manual through a hydraulic release system. The flywheel is bolted to the crank, the organic disc is clamped between the flywheel face and the pressure plate, and the release bearing pushes the diaphragm fingers when you press the pedal. The SB8-HDSS swaps all of those parts. ACT rates it at 259 ft-lb at the crank, which is 59 percent more holding power than the factory clutch, using an 8.8 in (224 mm) sprung organic disc on a 1 in input spline. The HD pressure plate raises clamp load with ACT's own diaphragm design, and the high-copper organic disc keeps engagement close to stock, which is why this is the kit most owners pick for a daily-driven car with bolt-ons or a mild tune.
This is a conversion kit. ACT states it must be used with the ACT flywheel that comes in the box, so do not plan on reusing the factory flywheel with these parts.
A true slip shows up as engine speed rising faster than road speed under load in a tall gear, usually third or fourth at low RPM with full throttle. Our slipping diagnosis guide walks through the road test and how to separate a slip from other drivetrain problems. If the pedal feels soft or the car will not go into gear with the engine running, bleed and inspect the slave and master cylinder first, because a hydraulic fault will make a new clutch feel bad too. Oil on the friction surface from a leaking rear main seal also causes chatter and slip, and it has to be fixed before the new disc goes in. See oil on the clutch disc.
Our listing is labeled 2013 Scion FR-S. ACT's application chart for SB8-HDSS covers the 2.0L FA20 cars: 2013-2016 Scion FR-S, 2013-2020 Subaru BRZ and 2017-2020 Toyota 86, plus the JDM 86. It does not fit the 2.4L GR86 or 2022-up BRZ. Engine and transmission swaps, or a car that already has an aftermarket flywheel, should be checked before ordering. If you are unsure, send us the year and VIN and we will confirm. Browse more parts on the clutch and rebuild kit page.
Use the supplied pilot bearing; pull the old one with a slide-hammer puller such as the OTC 1172. Install the flywheel with the new bolts torqued in a cross pattern to the factory spec, center the disc with the AT90 tool, then snug the pressure plate bolts evenly in a star pattern before final torque. Lube the input spline lightly, check the fork and pivot for wear, and bleed the hydraulics with fresh brake fluid. ACT says expect roughly 15 to 40 percent more pedal effort with a Heavy Duty plate, and recommends 300 to 500 miles of easy driving to break in the organic disc before any hard launches. Our clutch break-in guide covers the details.
Making more power than 259 ft-lb, or going to the track often? Step up to the SB8-HDG6 six-pad race kit or the SB8-XTSS Xtreme street kit. While the transmission is out, it is also the easy time to fit the DSS carbon fiber driveshaft.

No. ACT lists SB8-HDSS as a conversion kit that must be used with the ACT Prolite flywheel, and that flywheel is included in the box along with its bolts.
No. ACT's chart for SB8-HDSS covers the 2.0L FA20 cars: 2013-2016 FR-S, 2013-2020 BRZ and 2017-2020 Toyota 86. The 2.4L second-generation cars need a different kit.
ACT rates SB8-HDSS at 259 ft-lb measured at the crank, about 59 percent over the factory clutch. That suits bolt-ons and mild tunes; forced induction builds usually need a race disc.
Yes, somewhat. ACT says Heavy Duty pressure plates typically raise pedal effort by 15 to 40 percent depending on the car. Engagement stays smooth because the disc is a sprung organic street disc.
ACT recommends 300 to 500 miles of mild driving, such as stop-and-go city traffic, before hard launches or track use. Avoid overheating the clutch during that period to prevent glazing and hot spots.
The kit already includes the flywheel, release bearing, pilot bearing and alignment tool. Check the rear main seal for leaks, inspect the fork and pivot, and bleed the clutch hydraulics with fresh fluid.
