ACT 2013 Scion FR-S HD/Race Sprung 6 Pad Clutch Kit
ACT SB8-HDG6 is a complete clutch and flywheel conversion for the FA20-powered Scion FR-S, Subaru BRZ and Toyota 86. It is built for the owner whose six-speed car now has a supercharger, turbo kit or serious tune and is slipping the factory clutch in third and fourth, or for a track car that cooks organic discs every few events. Our listing is the 2013 Scion FR-S application, and ACT lists the same kit for the later twins as well.
The kit pairs ACT's Heavy Duty pressure plate with a 6-pad, spring-centered ceramic race disc and an ACT Prolite flywheel. The Heavy Duty plate uses ACT's own diaphragm design to raise clamp load and reduce deflection. The disc is 8.8 inches (224 mm) on a 1-inch input shaft, and its spring center damps torsional vibration so the hub survives hard launches. ACT currently rates the kit at 394 ft-lb measured at the crank, 142 percent over the stock clutch; some older catalogs still print a lower 349 ft-lb figure, so go by ACT's current page.
This is a conversion kit. ACT states the stock flywheel cannot be reused: you must run the included Prolite flywheel. Flywheel bolts (M10-1.0 x 25 mm) and pressure plate bolts (M8-1.25 x 16 mm) come in the box along with the disc, pressure plate, release bearing, pilot bearing and alignment tool. Shipping weight is about 25 pounds.
Be realistic about feel. ACT describes engagement as aggressive, with light to moderate pedal effort and OE to mild gear rattle, and recommends it for high-horsepower street or race use. On a stock or lightly modified daily driver the softer ACT HD/Perf Street Sprung kit (SB8-HDSS) is the better match.
Rule out the hydraulics first. A tired slave cylinder or air in the line causes drag and grinding into gear, not slip. Then do a third-gear pull from about 2,500 rpm at full throttle: if the tach jumps ahead of road speed, the disc is slipping. Our slipping diagnosis guide explains the test, and if you are not sure whether you have flare or true slip, read shift flare vs. slip. Check for oil on the bellhousing too; a leaking rear main seal will glaze any new disc.
Our listing covers the 2013 Scion FR-S. ACT's application chart for SB8-HDG6 also lists the 2013-2016 FR-S, 2013-2020 Subaru BRZ and Toyota 86 models with the 2.0L FA20, all manual. The second-generation 2.4L cars are not on the chart. ACT sells several FR-S kits with similar names, including SB13-HDG6 and the rigid-hub SB8-HDR6, so match the full ACT part number on your order, or send us your year and VIN and we will confirm it. More options are in our rebuild kits and clutch section.
If the car is making big power, the stock driveshaft is the next weak point; a DSS carbon fiber one-piece driveshaft is worth installing while the car is on the lift.

No. ACT lists SB8-HDG6 as a conversion kit and says you must use the ACT Prolite flywheel, which is included along with flywheel and pressure plate bolts.
ACT's chart lists the 2013-2020 BRZ and Toyota 86 with the 2.0L FA20 manual, plus the 2013-2016 FR-S. It does not cover the 2022-up 2.4L cars. Send us your year and VIN if you want us to confirm.
ACT's current product page rates it at 394 ft-lb at the crank, 142 percent over the stock clutch. Some older catalogs list 349 ft-lb.
It can be driven on the street, but engagement is aggressive and there may be mild gear rattle. ACT recommends it for high-horsepower street or race use. A stock or near-stock daily is better served by the SB8-HDSS street kit.
Check the rear main seal for leaks, inspect the release fork and pivot, bleed the clutch hydraulics, and refill the gearbox with fresh gear oil. Follow ACT's break-in before hard use.
