Clutch Masters 23-24 Toyota GR Corolla 1.6L Turbo 6-Speed Steel Flywheel
When a GR Corolla gets a clutch upgrade, the flywheel is the other half of the job. Owners shopping for FW-616-SF usually want sharper throttle response from the G16E-GTS three-cylinder, a fresh friction surface under a new clutch, or a flywheel that suits a street car better than a race-light aluminum part. Clutch Masters FW-616-SF is the lightweight steel flywheel for the 2023-2024 Toyota GR Corolla 1.6L turbo with the six-speed manual, built for Clutch Masters single disc clutch kits.
The flywheel carries the clutch, provides the friction face the disc clamps against, and stores rotating energy that smooths out idle and take-off. Less mass lets a small-displacement turbo engine rev and spool faster between shifts, but too little mass makes the car harder to launch and noisy at idle. Clutch Masters sets this steel version at 21 lb, which it describes as a good weight and feel for street-driven cars. Its aluminum FW-616-AL drops to 12 lb, and the maker says that one is meant for track use and will have significant gearbox chatter at idle.
The friction surface on FW-616-SF is a replaceable steel insert, so a worn or heat-checked face is replaced rather than machined. The flywheel is CNC machined, balanced and SFI certified, according to Clutch Masters.
Most flywheel problems show up once the gearbox is out, so inspect the face for hot spots, cracks and scoring and check runout before deciding. If the complaint is slip rather than judder, rule out low or contaminated clutch fluid and oil leaking onto the disc first. Our slipping diagnosis guide covers the checks, and the manual versus automatic repair cost breakdown helps you plan, since doing the clutch and flywheel together saves pulling the gearbox twice.
Clutch Masters lists FW-616-SF for the 2023-2024 Toyota GR Corolla with the 1.6L turbo and six-speed manual, and our listing matches those years. The maker describes it as a flywheel for its GR Corolla single disc clutch kits. It is not a part for the twin disc 725 Series, which ships with its own flywheel, and it does not apply to non-GR Corolla models. Morizo Edition cars use a different six-speed, so send your VIN before ordering for a Morizo or any car with a swapped gearbox. More parts are in our rebuild kits department.
Track-only car? The FW-616-AL aluminum flywheel saves another 9 lb at the cost of idle noise.
