Clutch Masters 2013 Ford Focus ST 2.0L Turbo 6-Speed Steel Flywheel
The Clutch Masters FW-212-SF is a single-mass steel flywheel for the Ford Focus ST with the 2.0L EcoBoost and six-speed manual, listed here for the 2013 model year. It is the part to look at when the factory dual-mass flywheel has started to rattle at idle, knock on takeoff or feel loose, and you are already pulling the transaxle for a stronger Clutch Masters clutch. It is a conversion part: it only works with a Clutch Masters single-disc kit, not with the stock clutch.
From the factory, the ST uses a dual-mass flywheel, two plates joined by springs that soak up engine pulses before they reach the gearbox. That keeps the car quiet, but the springs and bearing in the middle wear, and a tuned 2.0L puts far more torque through them than the stock 270 lb-ft. The FW-212-SF replaces that assembly with one solid piece. Clutch Masters machines it on CNC lathes from a 1045 steel billet, zero balances it, black-oxide coats it against rust and certifies it to SFI 1.2. It weighs 18 lb. That sits between the Clutch Masters FW-212-SF-HVY heavy steel version at 24 lb, which is close to the weight of the factory flywheel, and the FW-212-AL aluminum flywheel at about 9 lb. For a street ST, the 18 lb steel part is the middle ground: quicker revs than stock but enough mass to keep pulling away from a stop easy.
Listen at idle in neutral with the clutch out, then press the pedal. A rattle that changes with the pedal points at the flywheel or release bearing rather than the engine. If the complaint is rpm rising without acceleration, that is the clutch disc slipping, not the flywheel; our flare versus slip guide and the slipping diagnosis guide explain how to tell the difference. Rule out loose heat shields and exhaust contact before you plan the job.
Our listing names the 2013 Ford Focus ST 2.0L turbo with the six-speed manual. Clutch Masters lists FW-212-SF for the 2013 to 2017 Focus ST 2.0L 6-speed, so if you have a later ST, send us your year and VIN and we will confirm. It does not fit the standard Focus, the Focus RS or any Focus with the PowerShift automatic. Clutch Masters is clear that this flywheel will not work with the factory clutch or another brand's aftermarket kit, so pair it with a Clutch Masters FX100 to FX500 single-disc kit such as the FX400 6-puck sprung kit. It is not for the Clutch Masters 725 twin-disc kit, which uses its own twin-disc flywheel. More clutch and drivetrain parts are in our rebuild kits category.
With the transaxle out, remove the dual-mass flywheel and clean the crankshaft flange and bolt threads. This is the moment to check the rear main seal for weeping, since an oil leak will contaminate the new disc. Use new flywheel bolts and follow the thread locker and torque instructions supplied with the flywheel, tightening in a cross pattern. Wipe the friction face with brake cleaner to remove the protective film, center the disc with an alignment tool, and bring the pressure plate bolts down evenly. Bleed the clutch hydraulics with fresh fluid of the type marked on the reservoir cap and refill the gearbox with the Ford-specified manual transmission fluid. Expect a little more gear rattle at idle than with the dual-mass part; that is normal for a single-mass conversion. Clutch Masters asks for at least 500 miles of gentle driving to break in the new clutch.

No. Clutch Masters builds it as a conversion flywheel that only works with its own FX100 to FX500 single-disc clutch kits. It will not work with the factory clutch or another aftermarket brand's kit.
Clutch Masters lists this part for the 2013 to 2017 Focus ST 2.0L six-speed. Our listing is cataloged for 2013, so send us your VIN and we will confirm a later car before it ships.
Clutch Masters generally recommends steel for street cars because lighter flywheels make more gear noise. The 18 lb steel FW-212-SF is the middle option; the 24 lb heavy version drives closest to stock and the 9 lb aluminum suits track use.
Some added gear rattle at idle and a bit more vibration at low rpm is normal when you remove a dual-mass flywheel. The heavier the flywheel, the less of it you will notice.
A Clutch Masters single-disc kit is required, plus new flywheel bolts. Check the rear main seal and the clutch hydraulics while the transaxle is out.
No. The 725 series twin-disc kit uses a separate twin-disc flywheel. FW-212-SF is for the single-disc kits only.
