Clutch Masters 86-93 Toyota Supra 3.0L Eng T / 86+ Supra 1JZ Sprung FF Ceramic Disc
Many Mk III Supra owners need more clutch than an organic disc can give but still drive the car on the street. Clutch Masters 16063-HDCL is built for that driver. It is the FX400 kit with the 8-puck full-face ceramic disc, made for 7M-GTE Turbo and 1JZ cars running the R154 five-speed. It brings the same high-leverage pressure plate as the race-focused 6-puck version, with a disc tuned to stay civil in traffic.
The FX400 package uses the Power Plus I heavy-duty pressure plate. Clutch Masters rates the system at 170 percent more holding capacity than stock. The difference from the 6-puck kit is the disc. This one has eight segmented ceramic buttons laid out as a full face, with a Marcel cushion between the linings. The Marcel wafer lets the facings compress slightly as the clutch engages. That is why Clutch Masters calls this version the less aggressive one, with minimal chatter, and says it is designed for street-driven cars. The sprung hub also absorbs driveline shock, which the R154 and the rear end will thank you for.
The engagement is still ceramic, not stock. The manufacturer notes that ceramic discs are aimed at holding power and durability, not at longer life, and that easy commuting on ceramic can shorten clutch life.
Bleed the hydraulics and inspect the slave cylinder first, because a soft pedal that does not fully release feels like a bad clutch. To check for slip, cruise in fourth at about 2,000 RPM and floor it. A tach needle that jumps faster than road speed confirms it. Our article on flare versus slip explains what you are seeing. Before installing, look for oil at the bottom of the bellhousing, because a leaking rear main seal or input seal will ruin a fresh disc.
Per Clutch Masters, 16063-HDCL fits the 1986-1993 Supra 3.0L 7M-GTE with the R154 and the 1989-1993 Supra 2.5L 1JZ with the R154. The R154 came behind the turbo engine in US cars, while the naturally aspirated cars used the W58. A W58 car is not covered unless it has been converted. Engine and gearbox swaps are common on this chassis. Match the input spline and bellhousing to the R154 application, or send us the year and VIN before you buy. No flywheel is included. Browse our rebuild kits for other options.
If the car sees the track more than the street, the FX400 6-puck 16063-HDC6 is the harder-biting version, and the FX300 16063-HDTZ is a Kevlar step below both.

Both are FX400 kits with the same pressure plate and holding rating. HDCL has an 8-puck full-face ceramic disc with a Marcel cushion, so it engages more smoothly and is meant for street driving. HDC6 has a 6-puck disc with no Marcel, so it bites harder and may chatter.
Clutch Masters lists it for the 1989-1993 Supra 2.5L 1JZ with the R154. If your swap uses a different gearbox or bellhousing, confirm the parts against the R154 application before ordering.
The kit does not include one. Resurfacing the stock flywheel is the minimum. A worn or heat-checked flywheel will cause chatter even with a new disc.
Clutch Masters says ceramic discs are never recommended for stock or near-stock cars. Choose this kit when power has gone past what an organic or Kevlar disc will hold.
Use the brake fluid grade printed on your clutch or brake reservoir cap, and bleed the slave cylinder after the install.
