Clutch Masters 2023 Toyota Supra MK5 3.0L Turbo 6-Speed Lightweight Alumnium Flywheel
The Clutch Masters FW-340-AL is a lightweight aluminum flywheel for the 2023 Toyota GR Supra (MK5) 3.0L turbo with the six-speed manual. It replaces the factory dual-mass flywheel, and it is aimed at B58 owners who are upgrading the clutch for more power and want the engine to spin up and drop between shifts faster than the heavy stock unit allows.
Toyota fitted the manual Supra with a single-disc clutch and, as Clutch Masters puts it, a chunky dual-mass flywheel. That design soaks up the B58's firing pulses for a quiet idle, but its mass slows rev changes and its internal springs are another wear item once torque goes up. The FW-340-AL swaps it for a one-piece flywheel CNC machined in-house from a 6061 aluminum billet core, zero balanced, and Type 3 hard anodized. It carries SFI 1.2 certification for motorsport use.
The friction face is a replaceable steel insert. When the clutch is changed, you replace the insert instead of machining the flywheel, so the step height and flatness stay where Clutch Masters set them. The lower rotating mass is what delivers the claimed benefits: quicker revs and less of the lag you feel waiting for boost after a shift.
If the clutch is slipping, the flywheel is only part of the fix: pick the clutch first, then the flywheel that matches it. Clutch Masters notes that its single-disc covers bolt up to the factory flywheel, but because that flywheel is dual mass, keeping it requires a rigid-hub disc (or the FX500), while its standard sprung-hub kits are meant to pair with its lightweight steel or aluminum flywheel. To tell slip from other driveline complaints, use our slipping diagnosis guide and the flare versus slip explainer.
This listing is for the 2023 Toyota Supra MK5 3.0L turbo with the six-speed manual, the first model year the manual was offered. It does not fit automatic Supras, which use a flexplate and torque converter, or the 2.0L four-cylinder car. Later manual model years are not part of this listing; if you have a 2024 or newer car, send us the year and VIN so we can confirm before you order. More clutch parts are in our rebuild kits collection.
Prefer more mass for street driving? The FW-340-SF steel version is the same layout in a heavier 1045 steel body.

Clutch Masters designs its MK5 flywheels to pair with its own FX-series single-disc kits. Plan to install it with a matching Clutch Masters clutch rather than the factory disc.
Clutch Masters says its FX400 kits use a sprung hub meant for its lightweight flywheels. To keep the factory dual-mass flywheel you need a rigid-hub disc or the FX500 kit.
No. The friction surface is a replaceable steel insert, so you replace the insert instead of machining the flywheel.
No. It is listed for the 2023 Supra 3.0L turbo with the six-speed manual only.
The aluminum FW-340-AL gives the quickest rev response. The FW-340-SF steel version keeps more mass, which makes pulling away smoother in daily traffic.
