Clutch Masters 94-98 Toyota Supra 3.0L Turbo/ 1994+ Supra 2JZ Stage 8 Twin Disc Clutch Kit

Once a 1994-1998 Toyota Supra Turbo is running a single big turbo, more boost on the factory twins, or E85 tuning, the clutch is usually the first part to quit. If your Mk4 slips in fourth and fifth when boost comes in, the tach flares on a hard shift, or you are building a 2JZ-GTE that will make far more torque than the stock disc was ever rated for, this is the kit you are shopping for: Clutch Masters part number 16000-TD8S-SVH, an 850 Series street twin-disc clutch that comes with a steel flywheel and a hydraulic release bearing in the box.

What a twin-disc clutch does in a Mk4 Supra

A clutch holds torque through clamp load multiplied by friction area. A single-disc upgrade only has two friction faces, so the only way to hold more is a stiffer pressure plate and a more aggressive material, which costs you pedal effort and drivability. A twin-disc stack puts two smaller discs and a floater plate between the flywheel and pressure plate, so there are four friction faces sharing the load. Clutch Masters says its 850 Series uses a quick-release pressure plate it calls the QR system, built for clean engagement and release, and claims it cuts internal clutch noise by up to 50 percent while keeping pedal pressure manageable. The 8S in the part number marks the street version of the 850 line, as opposed to the race version.

The SVH suffix is what separates this kit from its siblings. Clutch Masters lists 16000-TD8S-SVH as steel flywheel and hydraulic release bearing included. The same 16000 kit is also offered with an aluminum flywheel (AVH) or with no flywheel (XVH). Steel adds weight compared with aluminum, which helps a heavy car leave from a stop and makes the clutch more forgiving in traffic.

Symptoms that point to a clutch upgrade

• Engine speed rises without the car accelerating in the upper gears once boost builds
• Slip that gets worse as the clutch heats up on repeated pulls
• Chatter or shudder leaving from a stop, often from a glazed disc or a hot-spotted flywheel
• Burning friction smell after a launch or a hill start
• Noise when the pedal is pressed, which points at the release bearing
• Grinding into gear or the car creeping with the pedal down, which points at release travel or hydraulics rather than the clutch itself

How to confirm before you buy

A twin disc is a big spend, so rule out the cheap causes first. Slip in high gear under load with a pedal that has normal free play is classic worn or overpowered friction. A pedal that engages near the floor, or a clutch that will not fully release, usually means air in the hydraulics or a failing master or slave cylinder; our clutch will not disengage guide walks through that. For slip diagnosis, see clutch slipping symptoms and fixes. If you are still deciding between a stout single disc and a twin, read twin disc vs single disc clutch differences. Clutch Masters itself says driving style and how the car is used should drive the choice more than a torque number.

Fitment

This listing is for the 1994-1998 Toyota Supra 3.0L Turbo with the 2JZ engine, and the vehicle data attached to the part shows the Supra. The US-market Turbo car came with the six-speed manual. Supras built with a different gearbox, engine swaps, and cars converted to an aftermarket transmission are a different story: we carry a separate 2JZ to T-56 twin disc kit for those builds. If your car has been swapped, modified, or imported, send us the year and VIN along with the transmission you are running and we will confirm before it ships.

Install notes

• Inspect the crankshaft pilot bearing and the transmission input shaft splines while everything is apart; a worn pilot causes noise and vibration that a new clutch will not fix.
• Clean the flywheel and pressure plate faces of any oil or assembly residue, then torque flywheel and pressure plate bolts evenly in a star pattern to the figures in the kit instructions.
• Use an alignment tool so the discs line up with the input shaft; a universal set like our 11-piece clutch alignment tool kit makes the job easier.
• The hydraulic release bearing replaces the factory throwout bearing, so plan how its line will be routed and bled. Our hydraulic clutch bleeding guide covers the process.
• Break-in is mandatory: Clutch Masters requires at least 500 miles of normal stop-and-go driving with no full-throttle shifts or compression braking before you put full power through it.

Does this kit include a flywheel?

Yes. The SVH version of Clutch Masters 16000-TD8S includes a steel flywheel and a hydraulic release bearing. The XVH version has no flywheel and the AVH version uses an aluminum flywheel, so check the suffix if you are comparing prices.

Will it fit a non-turbo 1994-1998 Supra?

This kit is listed for the 1994-1998 Supra 3.0L Turbo with the 2JZ. Non-turbo cars used a different manual gearbox, so do not assume it fits. Send us your year, VIN and transmission and we will confirm before ordering.

Is the 850 Series streetable?

Clutch Masters builds the 850 Series street twin disc for cars that are driven on the street and the track, and says its QR pressure plate keeps pedal pressure manageable and reduces internal noise. Expect a twin disc to engage more quickly than a stock clutch.

What should I replace at the same time?

Inspect or replace the crankshaft pilot bearing, check the input shaft splines and the rear main seal for leaks, and replace any tired clutch hydraulic parts. Oil on a new clutch will cause chatter and slip.

How long is the break-in?

Clutch Masters requires a minimum of 500 miles of normal stop-and-go driving, with no full-throttle shifting or compression braking, so the friction material seats against the flywheel and pressure plate.

Is there a warranty?

Yes, this kit carries a 1-year warranty, and it is new Clutch Masters product shipped from the USA.
