ACT 2013 Scion FR-S HD/Perf Street Sprung Clutch Kit
ACT SB7-HDSS is a complete street clutch package for the first-generation Scion FR-S, Subaru BRZ and Toyota 86 with the 2.0L FA20 and six-speed manual. It is aimed at the owner whose factory clutch is worn out or starting to slip after an intake, header and tune, and who still drives the car every day. If your FR-S flares in third at the top of the rev range, judders pulling out of a parking spot, or has an engagement point that has crept to the top of the pedal, this kit replaces every wear part in one job.
This is a conversion kit, so the factory flywheel comes out and ACT's own flywheel goes in. The box holds the 600480 XACT Streetlite flywheel, the SB024 Heavy Duty pressure plate, the 3000506 Performance Street sprung disc, an RB004 release bearing, a PB1004 pilot bearing and the AT90 alignment tool, plus flywheel bolts (M10-1.0 x 25 mm) and pressure plate bolts (M8-1.25 x 16 mm).
The Heavy Duty diaphragm adds clamp load without a heavy pedal, and the organic disc uses a high-copper, steel-backed lining with a sprung hub, so it engages like a stock clutch and soaks up driveline shock. ACT rates the kit at 259 ft-lb at the crank, 59 percent over the factory clutch, on an 8.8 in (224 mm) disc with a 1 in input shaft. That leaves plenty of margin for a naturally aspirated FA20 and for many mild forced-induction setups.
The Streetlite flywheel is the reason to pick SB7 over its twin. ACT lists the 600480 at 12.9 lb in chromoly steel, with a 228 mm friction face and 124 ring-gear teeth, and calls it its most durable flywheel. The SB8-HDSS uses the same plate and disc with the lighter Prolite flywheel, which revs faster but is less forgiving at idle and on slow takeoffs. For a car that spends its life in traffic, the Streetlite is the easier one to live with.
Rule out the hydraulics first. A soft pedal or grinding into gear points to air in the line or a weak slave cylinder, not a worn disc. To check for slip, pick third gear at low rpm, go to full throttle and watch the tach against road speed; a needle that jumps ahead means the disc cannot hold. Our slipping diagnosis guide lays out the steps, and shift flare vs. slip helps you tell a true slip from other drivetrain feel. Check the bellhousing for oil as well, because a rear main seal leak will spoil a new disc within weeks.
Our listing is for the 2013 Scion FR-S. ACT's chart for SB7-HDSS covers the 2013-2016 Scion FR-S, 2013-2020 Subaru BRZ and 2017-2020 Toyota 86, plus the JDM Toyota 86, all with the 1998 cc FA20 engine and manual gearbox. The 2022-up BRZ and GR86 with the 2.4L engine are not on that chart. ACT sells several FR-S kits whose names differ by a single digit, so make sure your order reads SB7-HDSS, or send us your year and VIN and we will confirm it. More clutch parts are in our rebuild kits section.
If the car will see more power later, compare the SB7-HDG6 race kit, which shares this flywheel but uses a ceramic six-pad disc.

Yes for the first generation. ACT lists the 2013-2016 FR-S, 2013-2020 BRZ and 2017-2020 Toyota 86 with the 2.0L FA20 manual. The 2.4L cars from 2022 on are not listed.
The plate, disc and 259 ft-lb rating are the same. SB7-HDSS includes the 600480 Streetlite flywheel; SB8-HDSS includes the lighter Prolite flywheel.
No. This is a conversion kit and ACT says its included flywheel must be used. Flywheel bolts and pressure plate bolts are in the box.
ACT describes light to moderate pedal effort, smooth positive engagement and OE to mild gear rattle, and the organic sprung disc behaves much like stock in traffic.
The clutch hydraulics use brake fluid; use the DOT grade in your owner's manual when you bleed the system. It is also a good time to refill the six-speed with the gear oil the manual specifies.
