Clutch Masters 2023 Toyota Supra MK5 3.0L Turbo 6-Speed FX1000 Twin Disc Clutch Kit w/Alum. Flywheel
Toyota added a six-speed manual to the GR Supra for the 2023 model year, and B58 owners started turning the boost up almost immediately. The factory pairs that gearbox with a single-disc clutch and a heavy dual-mass flywheel, which is fine at stock power but quickly runs out of clamp once the engine is tuned, fueled on ethanol or fitted with a bigger turbo. Clutch Masters part number 16340-TDKR-A is its FX1000 twin-disc clutch for the 2023 Supra 3.0L manual, sold with an aluminum flywheel, for cars making serious power that still get driven on the street.
From the factory the B58 makes roughly 365-369 lb-ft, and a tuned engine can make far more. A single disc can only hold so much before it slides, so the FX1000 spreads the clamp load over two friction discs with an intermediate plate between them. Clutch Masters says the 1000 Series is designed to hold well over 1,000 lb-ft, and its strap-driven plates keep engagement smooth with little chatter while still surviving hard launches, clutch kicks and high-rpm shifts. Replacing the dual-mass flywheel with the included aluminum flywheel removes a lot of rotating weight, so the engine revs and drops faster between shifts. Clutch Masters is clear that its torque ratings are estimates and that how the car is driven matters as much as the dyno number.
A slip test is simple: in fourth gear at low rpm, go to full throttle and see whether engine speed climbs faster than road speed. A data log makes it obvious. Before blaming the disc, check the clutch hydraulics for a soft pedal, a leak at the bellhousing or a pedal that does not return fully. Then be honest about the build. If the car makes moderate power and is mostly a daily driver, the Clutch Masters FX400 single-disc kit for the 2023 Supra or an ACT Mod-Twin 225 HD sprung street kit may be the better match. Our manual vs automatic repair cost guide helps you budget the labor.
This kit is listed for the 2023 Toyota GR Supra MK5 with the 3.0L turbo six and the six-speed manual. The manual was only offered with the six-cylinder, so it does not fit 2.0L cars, and it does not fit any Supra with the eight-speed automatic. Later model years with the same manual may share parts, but the fitment we can confirm is 2023, so send us your year and VIN before ordering for a 2024 or newer car. If you are building a dedicated drag car instead, the flywheel is also sold on its own as the Clutch Masters lightweight aluminum flywheel for the 2023 Supra, though this kit already includes one.
Expect some intermediate-plate noise at idle with the pedal down and more gear rattle at idle than with the dual-mass flywheel. Both are normal with a twin disc and a light flywheel.

No. It is for the 3.0L six-cylinder with the six-speed manual, which Toyota offered from the 2023 model year. Automatic cars have no clutch, and the 2.0L was not sold with the manual.
The fitment we can confirm for this part number is 2023. Send us your year and VIN and we will check it before you order a newer car.
No. The kit includes an aluminum flywheel that replaces the dual-mass unit, and the clutch is designed to work with it.
Clutch Masters says the 1000 Series is designed to handle well over 1,000 lb-ft, but it also says its ratings are estimates and that driving style and use matter as much as power.
Yes, within reason. The strap-driven plates are there to give smooth engagement with little chatter, but expect a firmer pedal, more idle rattle and a quicker bite than the factory clutch.
