ACT 2013 Scion FR-S XT/Perf Street Sprung Clutch Kit
ACT SB7-XTSS is the clutch package for a first-generation Scion FR-S, Subaru BRZ or Toyota 86 that now makes more torque than a Heavy Duty clutch is happy with. Owners usually land here after a supercharger or turbo kit: the stock clutch, or a milder upgrade, starts to flare on boost in third and fourth, and the car can no longer put its new power down. This kit pairs ACT's Xtreme pressure plate with an organic street disc and a steel Streetlite flywheel, so it holds far more than stock while still driving like a street car.
ACT rates SB7-XTSS at 366 ft-lb measured at the crank, which it lists as 125 percent over the factory clutch. That is a big step past the 259 ft-lb Heavy Duty version of the same kit, and it comes from the Xtreme diaphragm, which raises clamp load and reduces deflection. The disc is ACT's Performance Street sprung organic design, 8.8 in (224 mm) on a 1 in input shaft, with a high-copper lining for heat transfer and a sprung hub to soften engagement and damp driveline shock.
It is a conversion kit. ACT's component list for SB7-XTSS names the 600890 Streetlite flywheel (12.9 lb chromoly, 124 teeth), the SB023 pressure plate, the 3000507 sprung disc, an RB004 release bearing, a PB1004 pilot bearing and the AT90 alignment tool, and ACT notes that flywheel bolts (M10-1.0 x 25 mm) and pressure plate bolts (M8-1.25 x 16 mm) are in the box. ACT's catalog page for SB023 calls it a Heavy Duty plate while the kit spec sheet lists an Xtreme plate, so check the labels when your box arrives and call us if anything does not match.
The trade-off is pedal feel. ACT describes the Xtreme kit as moderate to heavy pedal effort and says its Xtreme plates typically add 50 to 80 percent pedal effort, depending on the car. On a stock FR-S that is noticeable in traffic, which is why this kit is meant for built cars.
Rule out hydraulics first: a spongy pedal or grinding into gear is usually air in the line or a tired slave cylinder rather than a worn disc. For slip, use a higher gear at low rpm and go to full throttle while watching the tach; a needle that jumps ahead of road speed is a clutch that cannot hold. Our guide to diagnosing slipping walks through it, and shift flare vs. slip explains the feel. Look for oil at the bellhousing too, because a rear main seal leak will contaminate any new disc.
Our listing is for the 2013 Scion FR-S. ACT's application chart for SB7-XTSS covers the 2013-2016 Scion FR-S, 2013-2020 Subaru BRZ and 2017-2020 Toyota 86, plus the JDM 86, all with the 1998 cc FA20 and manual gearbox. The 2.4L BRZ and GR86 from 2022 on are not listed. ACT sells several FR-S kits that differ by one character, so confirm your order reads SB7-XTSS, or send us the year and VIN and we will check it. More clutch parts are in our rebuild kits section.
If you want the same plate with less flywheel mass, compare the SB8-XTSS Prolite version. For a lighter pedal on a mildly modified car, the SB7-HDSS Heavy Duty kit uses the same flywheel style.

Yes for the first-generation 2.0L FA20 manual cars: ACT lists the 2013-2016 FR-S, 2013-2020 BRZ and 2017-2020 Toyota 86. The 2.4L cars from 2022 on are not on the chart.
ACT rates it at 366 ft-lb at the crank, 125 percent over the factory clutch. The Heavy Duty SB7-HDSS is rated at 259 ft-lb.
Yes. ACT describes moderate to heavy pedal effort and says Xtreme plates usually add 50 to 80 percent pedal effort. It suits boosted or heavily built cars better than a stock daily driver.
Both carry the same 366 ft-lb rating, plate and disc. SB7-XTSS comes with the 12.9 lb 600890 Streetlite flywheel; SB8-XTSS comes with the 8.4 lb 600895 Prolite flywheel.
ACT recommends 300 to 500 miles of mild, stop-and-go driving for its organic street discs before launches or track use, and warns against overheating the clutch during that time.
