Clutch Masters 2023 Toyota Supra MK5 3.0L Turbo 6-Speed FX400 6-Puck Clutch Kit
Clutch Masters 16340-SSC6 is the FX400 six-puck kit from the Short Shift series for the 2023 Toyota GR Supra 3.0L turbo with the six-speed manual. It is meant for B58 owners who added a tune, intake or turbo work and now feel the factory clutch slip in the upper gears. Clutch Masters says MK5 owners began calling about slipping clutches with simple bolt-ons and a tune shortly after the manual car arrived.
The Supra manual ships with a single-disc clutch and a heavy dual-mass flywheel. This kit replaces the stamped steel cover with a billet aluminum OE-style cover using the diaphragm from the Clutch Masters 850 Series twin disc plus a modified pivot point. The maker says that combination raises clamp load and shortens the pedal throw needed to release the clutch, while the stiffer cover flexes less than stamped steel and weighs about 10% less. The FX400 disc is a six-puck segmented ceramic on a sprung hub, built for rapid engagement. Clutch Masters describes it as primarily a track clutch that can be driven on the street, with very aggressive engagement.
Log a fourth-gear pull and compare engine speed with wheel speed; a gap that grows near peak torque confirms slip. Check the brake fluid reservoir level, which feeds the clutch hydraulics on this car, and make sure the pedal returns fully. Rule out an oil leak at the rear main seal. Our guide to manual transmission repair cost helps you budget the job.
This listing is confirmed for the 2023 Toyota Supra MK5 3.0L turbo with the six-speed manual. It does not fit the eight-speed automatic or the 2.0L four-cylinder. For later model years, send your year and VIN so we can verify the part number before shipping. Important: the FX400 uses a sprung hub, and Clutch Masters recommends pairing its sprung-hub kits with a lightweight flywheel instead of the factory dual-mass unit. Plan on the Clutch Masters lightweight steel flywheel or the aluminum flywheel. More kits are in our rebuild kits collection.

Clutch Masters says the cover bolts to the factory flywheel, but the FX400 uses a sprung hub and the maker recommends its lightweight steel or aluminum flywheel with sprung-hub kits. Keeping the dual-mass flywheel requires a rigid-hub disc instead.
It works on the street, but Clutch Masters calls it primarily a track clutch with very aggressive engagement. Expect some chatter in first and reverse.
