Ceramic Six-Pad Race Clutch Disc for Maximum Torque on the FA20 Platform
The ACT 6224218-1 is a 6-Pad Sprung Race clutch disc engineered for the 2013-2020 Subaru BRZ, 2013-2016 Scion FR-S, and 2013-2020 Toyota 86. Where the street-spec organic disc is built for smooth daily engagement, the 6224218-1 is built for drivers who push their FA20 platform hard at the track. The ceramic six-pad design dramatically increases friction surface contact area, expanding heat capacity and extending disc life under sustained high-temperature track conditions. Engagement is noticeably firmer and shift action is faster than a street disc. The spring-centered hub uses heavy-duty torsional dampening springs that are stronger than standard springs, sized and rated specifically for the application, to absorb shock while maintaining fast mechanical response. The 6224218-1 must be used with an ACT pressure plate and is recommended for larger clutch sizes where extra heat absorption and smooth engagement under load are priorities.

Frequently Asked Questions
What is the ACT 6224218-1?The ACT 6224218-1 is a 6-Pad Sprung Race clutch disc for the 2013-2020 Subaru BRZ, 2013-2016 Scion FR-S, and 2013-2020 Toyota 86. It uses ceramic friction material across six pads with a heavy-duty spring-centered hub for high-torque track applications where maximum heat resistance is required.
Is this disc suitable for street driving?The 6224218-1 is a race-oriented disc. Engagement is firmer and less progressive than the organic street disc. It can be driven on the street but is not optimized for smooth low-speed city traffic. If you need a disc that is comfortable for daily commuting and occasional track use, the ACT 3000504 or ACT3000506 is a better choice.
Why does the 6-pad design provide better track performance?The six ceramic pads distribute clamping force across a larger total contact area, which reduces heat concentration per pad, delays fade onset during extended braking and repeated hard launches, and extends disc service life under sustained track conditions compared to a full-face organic disc in high-heat environments.
What pressure plate is required with the 6224218-1?The 6224218-1 must be used with an ACT pressure plate. ACT Heavy Duty and Xtreme pressure plates are both compatible with this disc on the FA20 platform. Do not use with the OEM pressure plate.
Does this disc fit the 2018 Subaru BRZ TS?Yes. The ACT 6224218-1 fits the 2018 and 2020 Subaru BRZ TS in addition to all other listed BRZ, FR-S, and 86 trims on the FA20 platform.
Do I need to replace the release bearing at the same time?Yes, it is strongly recommended. The ACT RB004 is the correct direct-fit release bearing for the FR-S, BRZ, and 86 platform and is available separately on our site.
Is an alignment tool required for installation?Yes. The ACT AT90 clutch alignment tool is the correct tool for this application. Proper centering of the disc is critical for smooth transmission input shaft engagement during reinstallation.
How does clutch break-in differ for a ceramic disc?Ceramic discs require a specific heat-cycling break-in procedure. Avoid hard launches or high-slip engagement for the first 200-500 miles. Perform several moderate acceleration runs from low speed to allow the pads to seat evenly against the flywheel and pressure plate surfaces before full-power use.
Installation Instructions
- Safely lift and support the vehicle and remove the driveshaft and transmission.
- Remove the OEM pressure plate and clutch disc assembly.
- Inspect and resurface or replace the flywheel friction surface as needed.
- Install the ACT 6224218-1 disc using the ACT AT90 alignment tool or equivalent to center it in the spline bore.
- Install the ACT pressure plate and torque the bolts to factory spec in a star pattern.
- Replace the release bearing with ACT RB004 or equivalent.
- Reinstall the transmission and driveshaft to factory torque specifications.
- Follow ACT's ceramic disc break-in procedure before sustained track use.

Clutch Discs
The clutch disc is the friction component that sits between the flywheel and pressure plate, transferring engine torque to the transmission input shaft on engagement. Choosing the right friction material for your power level and driving style determines how long the disc lasts and how the clutch engages under load.Popular UpgradesOrganic friction discs are the standard choice for street builds, providing smooth engagement and long service life at stock to moderately modified power levels. Ceramic and Kevlar friction discs are designed for high-output, high-heat applications where organic materials would glaze or fade under sustained torque load. Sprung hub discs with torsional dampening springs reduce driveline shock on street applications and are recommended for daily-driven builds.What clutch disc material is best for a turbocharged engine?Ceramic or Kevlar-composite friction materials are best suited for turbocharged and supercharged engines that produce high torque spikes. These...
