Clutch Masters 23-24 Toyota GR Corolla 1.6L Turbo 6-Speed FX100 Clutch Kit - 395ft/lbs Torque

If the factory clutch in your 2023-2024 Toyota GR Corolla is wearing out, slipping on a hard pull, or chattering when you pull away, and you want a replacement that lasts longer without changing how the car drives, the Clutch Masters FX100 kit (16616-HD00) is the mildest step in the Clutch Masters GR Corolla lineup. It is a single-disc organic kit made for the 1.6L turbo six-speed, rated at 395 ft-lb in our listing, and built to feel close to stock in traffic.

What the FX100 clutch kit does in a GR Corolla

The GR Corolla's turbocharged three-cylinder drives through a single-plate clutch into the six-speed manual, and from there into the GR-Four all-wheel-drive system. Because all four tires grip at once, a launch or a fast upshift puts the shock straight into the clutch instead of letting a front tire spin it off. The FX100 keeps the factory-style layout but swaps in Clutch Masters' Power Plus I heavy-duty pressure plate and a heavy-duty disc with steel-backed organic lining over a marcel spring wafer. Clutch Masters rates the system at a 70 percent increase in holding capacity over stock. The maker describes the feel as only slightly heavier pedal effort than factory, with normal, smooth engagement and longer life than the original clutch.

Be realistic about where it sits. Clutch Masters writes the FX100 description for cars with light bolt-ons such as an intake or exhaust, not big turbo or heavy tune builds. On a GR Corolla that means a stock car or a lightly modified one. If you are running an aggressive tune or plan to, look at the FX350 kit rated at 450 ft-lb instead.

Symptoms that mean the clutch is due

• RPM rises without a matching gain in speed, usually first in third or fourth gear at full boost
• Shudder or judder pulling away from a stop or backing up a slope
• A burnt friction smell after a launch, a steep hill or a track session
• The engagement point creeping higher in the pedal travel as the disc thins
• Squeal, chirp or rumble that changes when you press the pedal, which points to the release bearing
• Gears that grind going in because the clutch is not fully releasing

How to confirm it before you buy

Do a controlled slip test on an empty road: fourth gear, low RPM, then full throttle while you watch the tach against the speedometer. If RPM jumps ahead of road speed, the disc is slipping. Before you commit to pulling the transaxle, rule out the hydraulics. Air in the line or a weeping master or slave cylinder can hold the clutch partly released and mimic a worn disc, or make it hard to get into gear. Bleed the system and check for fluid at the slave first. Our slipping diagnosis guide walks through separating clutch slip from other driveline problems, and the GR Corolla clutch upgrade buyer's guide compares the steps if you are still deciding.

Fitment

Clutch Masters lists 16616-HD00 for the 2023-2024 Toyota Corolla GR 1.6L turbo with the six-speed manual, and that is exactly what our listing covers. Clutch Masters does not break out the Morizo Edition separately, and the Morizo uses a different gearbox, so Morizo owners should send their VIN before ordering. The 2025 and later cars, including those with the automatic, are not on this listing. If anything about your car has been changed, send us the year and VIN and we will confirm the part number before it ships. The rest of our GR Corolla clutches and flywheels are in the clutch and rebuild kit collection.

Install notes

• The kit includes the heavy-duty disc, the Power Plus I pressure plate, an OEM-or-better release bearing, an alignment tool, an instruction card and decals. A pilot bearing is supplied only where the application uses one. No flywheel is included.
• Resurface the stock flywheel or replace it. For a street car, the FW-616-SF steel flywheel keeps the car smooth at idle; a lightweight flywheel sharpens throttle response but adds gear rattle and, per Clutch Masters, can shorten organic clutch life. Our lightweight vs stock flywheel guide covers the trade-off.
• The transaxle has to come out, and on an all-wheel-drive car that means separating the front driveline from the transfer case, so budget a full clutch job of labor.
• Center the disc with the supplied tool, or a universal clutch alignment tool kit, and tighten the pressure plate bolts gradually in a crisscross pattern to the factory torque.
• Bleed the hydraulics with fresh fluid of the type marked on the reservoir cap, then check the engagement point and free play.
• Break it in gently. Clutch Masters notes that break-in, driving style and power upgrades all affect organic clutch life. See our clutch break-in guide.

The kit is new, in stock and ships from the USA the same business day, backed by a 1-year warranty.

Does the FX100 fit a 2023 or 2024 GR Corolla Core or Circuit Edition?

Yes. Clutch Masters lists 16616-HD00 for the 2023-2024 Corolla GR 1.6L turbo six-speed. The Morizo Edition uses a different gearbox, so send us that VIN before ordering.

Is the FX100 enough for a tuned GR Corolla?

It is the mildest step. Clutch Masters writes it for light bolt-ons like an intake or exhaust. For an aggressive tune or bigger turbo, the FX350 or the ceramic FX400 and FX500 kits are the better match.

Will the pedal feel heavier than stock?

Only slightly. Clutch Masters describes the FX100 as having slightly increased pedal pressure over factory with normal, smooth engagement.

Does the kit include a flywheel?

No. It includes the disc, pressure plate, release bearing, alignment tool, instructions and decals, plus a pilot bearing only where the car uses one. Resurface your flywheel or pair it with the FW-616-SF steel flywheel.

What fluid do I use when I bleed the clutch?

Use the brake fluid type printed on the clutch or brake reservoir cap of your car. Flush in fresh fluid while the system is open.

How long should I break in the new clutch?

Drive it gently for the first few hundred miles with no launches or hard, high-RPM engagements. Follow the instruction card that ships with the kit.
