ACT 2013 Scion FR-S HD/Race Sprung 6 Pad Clutch Kit
ACT SB7-HDG6 is a ceramic race clutch package for the first-generation Scion FR-S, Subaru BRZ and Toyota 86. It suits a six-speed FA20 car with forced induction or a hard track schedule that has outgrown the factory clutch, but where the owner wants a flywheel with a little more mass than ACT's lightest option. If your FR-S slips under boost, smells hot after a session, or is due for a clutch and you plan to add power, read on.
The kit combines the SB024 Heavy Duty pressure plate, the 6228218-1 six-pad sprung race disc and the 600480 XACT Streetlite flywheel. The rest of the box covers the parts that usually get missed: an RB004 release bearing, a PB1004 pilot bearing, the AT90 alignment tool, flywheel bolts (M10-1.0 x 25 mm) and pressure plate bolts (M8-1.25 x 16 mm). ACT lists it as a conversion kit, so the stock flywheel is not reused.
The six ceramic pads concentrate the Heavy Duty plate's clamp load and tolerate heat that would fade an organic lining, while the spring center damps driveline vibration. ACT rates the kit at 394 ft-lb at the crank, 142 percent over stock, with an 8.8 in (224 mm) disc on a 1 in input shaft.
The SB7 and SB8 versions of this kit share the same plate and disc rating. The difference is the flywheel: SB7-HDG6 uses the Streetlite, while the SB8-HDG6 comes with the lighter Prolite. The Streetlite keeps a bit more rotating mass, which can help an FR-S pull away smoothly from a stop and hold revs between shifts on the street. Kit shipping weight is about 26.6 lb.
ACT describes the feel as light to moderate pedal effort, aggressive engagement and OE to mild gear rattle, and recommends it for high-horsepower street or race use. A near-stock daily driver will be happier with the organic SB7-HDSS street kit.
Check the clutch hydraulics before replacing parts: a failing slave cylinder or air in the line shows up as grinding into gear or a soft pedal, not as slip under load. Then run a third-gear pull from low rpm at full throttle and watch whether the tach jumps ahead of road speed. Our slipping diagnosis guide walks through it, and shift flare vs. slip explains the difference. Look for oil at the bellhousing too; a rear main seal leak will ruin a new disc.
Our listing covers the 2013 Scion FR-S. ACT's chart for SB7-HDG6 lists the 2013-2016 Scion FR-S, 2013-2020 Subaru BRZ and 2017-2020 Toyota 86 with the 2.0L FA20 (1998 cc), manual transmission. It does not list the 2022-up 2.4L cars. Because ACT sells many FR-S kits with similar names, confirm that your order reads SB7-HDG6, or send us your year and VIN and we will check it. More clutch parts are in our rebuild kits section.
Big-power FR-S builds often break the driveshaft next. The DSS carbon fiber one-piece driveshaft is worth fitting while the transmission tunnel is open.

No. The 600480 Streetlite flywheel, flywheel bolts, pressure plate bolts, release bearing, pilot bearing and alignment tool are all in the kit, and ACT says the ACT flywheel must be used.
ACT recommends it for high-horsepower street or race use, with aggressive engagement and OE to mild gear rattle. On a stock or lightly modified daily, the SB7-HDSS organic kit is smoother.
ACT rates SB7-HDG6 at 394 ft-lb measured at the crank, 142 percent over the stock clutch.
