Clutch Masters 86-93 Toyota Supra 3.0L Eng T / 86-Up Toyota Supra 1JZ / 91-93 Toyota Supra 3.0L Eng
If your Mk III Supra Turbo or 1JZ-swapped A70 now makes enough boost to spin the clutch in third gear, the stock-style disc has hit its limit. Clutch Masters part 16063-HDC6 is the FX400 kit in its 6-puck form: a sprung ceramic button disc behind a heavy-duty, high-leverage pressure plate, built for 7M-GTE and 1JZ cars running the R154 five-speed. It is the more aggressive of the two FX400 versions and is meant for cars that see the drag strip, road course or very hard street use.
In the R154 the clutch is the only link between a turbo six and the input shaft, and the disc has to survive repeated full-boost launches and fast shifts. The FX400 pairs the Power Plus I pressure plate with a disc that carries six ceramic pucks instead of a full ring of facing. Clutch Masters rates the system at a 170 percent increase in holding capacity over stock. The pucks are riveted solid with no Marcel cushion, so engagement is quick and almost on-off. The sprung hub adds a moderate amount of damping, which keeps it more livable than a solid-hub race disc.
Clutch Masters is direct about the tradeoff: the 6-puck disc may chatter slightly in first and reverse, and ceramic discs are never recommended for stock or near-stock cars. If the car is a daily driver, look at the 8-puck version below first.
Rule out hydraulics first. A weak master or slave cylinder, or air in the line, causes drag and hard shifts that look like a worn clutch. Then do a load test: in fourth gear at low RPM, go to full throttle and watch the tach. If engine speed jumps ahead of road speed, the disc is slipping. Our slipping diagnosis guide walks through telling real slip apart from other problems. Also pull the inspection cover and check for oil on the bellhousing. A leaking rear main seal will contaminate any new disc, ceramic included.
Clutch Masters lists 16063-HDC6 for the 1986-1993 Toyota Supra 3.0L 7M-GTE turbo with the R154 five-speed and the 1989-1993 Supra 2.5L 1JZ turbo with the R154. Keep in mind that US naturally aspirated A70s left the factory with the W58 gearbox, not the R154. Those cars, and any car with a swapped gearbox, need the transmission confirmed before ordering. Swaps vary, so match your input shaft and bellhousing to the R154 application or send us your year and VIN. The flywheel is not part of this kit. Other clutch options for these cars are in our rebuild kits section.

US naturally aspirated A70s came with the W58 five-speed. This kit is listed for the R154 used in 7M-GTE and 1JZ cars, so a W58 car needs a different kit unless it has been converted to an R154.
Clutch Masters warns it engages quickly and may chatter slightly in first and reverse. It also says ceramic discs are not recommended for stock or near-stock cars. For a street car, the 8-puck 16063-HDCL is the less aggressive choice.
No. The kit has a pressure plate, a 6-puck ceramic disc, a release bearing, a pilot bearing when applicable, and an alignment tool. Resurface your flywheel or buy one separately.
Clutch Masters rates the FX400 system at a 170 percent increase in holding capacity over stock.
Replace the pilot bearing, and resurface or replace the flywheel. Check the slave and master cylinders and the rear main seal while the transmission is out.
