PMC Clutch lightweight flywheel Ford Fiesta ST / ST200 1.6 EcoBoost (JTJA, JTJB, JTJC) – 228 mm / 8.98" – 5.71 kg / 12.59 lbs (−50% vs OE)
Lightweight single-mass flywheel (SMF) PMC Clutch for the Ford 1.6 EcoBoost engine (JTJA, JTJB, JTJC), installed in the Ford Fiesta ST (182 hp) and Fiesta ST200 (200 hp). The flywheel is a direct replacement for the factory Ford OE C1BY-6477-BC / C1BY-6477-BD / C1BY-6477-BE (2041312, 1785385, 5897251) flywheel – installed plug & play without any adapter or modifications, as all mounting points are retained exactly like the stock unit. The flywheel body is CNC-machined from aluminum, featuring a replaceable steel friction plate and a zinc-plated starter ring gear. The flywheel works with the factory Ford 228 mm clutch (OE pressure plate C1BY-7563-BD, OE friction disc C1BY-7550-BC) as well as any OE-fit aftermarket or custom clutch – for example Sachs 3000 951 550, Sachs Performance 3000 951 550-S, or LuK 623 3744 09. Flywheel bolts are included in the kit.
The factory flywheel weighs 11.33 kg / 24.98 lbs, whereas the PMC Clutch flywheel weighs 5.71 kg / 12.59 lbs, representing a 50% weight reduction – over 5.6 kg less rotational mass directly off the crankshaft. Lower inertia allows the turbocharged 1.6 EcoBoost engine to rev up faster and drop revs quicker off throttle, making rev-matching on downshifts significantly easier and sharper. While engine horsepower remains unchanged, drivetrain losses are reduced, delivering more usable power to the wheels. A lightweight flywheel performs exceptionally well on technical, twisty circuits where the car regains exit speed much faster – an ideal upgrade for a daily-driven Fiesta ST as well as track day, rallycross, and time attack setups.
PMC Clutch flywheels are engineered using 3D scanning of original factory components, with the dimensional accuracy of every batch inspected via a measuring arm. Manufacturing takes place on modern CNC machining centers, guaranteeing repeatability and perfect concentricity with the crankshaft. Every flywheel is balanced prior to dispatch and engraved with an individual production serial number.
All of our manufacturing and R&D engineering department are based in Poland. Over 90% of components are manufactured in-house by our company.

Additional Information
PMC Motorsport parts are intended for motorsport and closed racetrack use only.
Components intended for installation by professionals with expertise in engine swaps and automotive modifications – in specialized workshops using appropriate tools.
The installation instructions contain only the essential information necessary for the correct installation of the flywheel and clutch.
Depending on the specific vehicle and the condition of the remaining drivetrain components, additional servicing procedures may be required.
Our flywheels are manufactured from materials that are 100% recyclable.
Installation Instructions
The PMC Clutch flywheel mounts directly in place of the factory Ford OE C1BY-6477-BC / BD / BE flywheel, without any adapter or modifications – the mounting points are identical to the OE unit. Crankshaft bolts are included in the kit; they must be torqued to 80 Nm / 59 lb⋅ft using threadlocker. Pressure plate mounting bolts and washers are also included in the kit. Select a 228 mm / 8.98" clutch kit designed for the Fiesta ST 1.6 EcoBoost – factory Ford C1BY-7563-BD pressure plate with C1BY-7550-BC friction disc or any aftermarket/custom clutch compliant with OE mounting points (see compatibility table for part references). We recommend checking the condition of the release system prior to assembly.
Frequently Asked Questions
Which cars and engines is this flywheel compatible with?
The flywheel is designed for the Ford Fiesta ST (182 hp, 1.6 EcoBoost JTJA / JTJB engine) and Fiesta ST200 (200 hp, JTJC) with manual transmissions – listed in parts catalogs as Fiesta VI (CB1, CCN), and commonly referred to in Poland and the UK as the Fiesta Mk7 ST.
Is this a direct replacement for the OE flywheel?
Yes. The PMC Clutch flywheel replaces factory Ford OE C1BY-6477-BC, C1BY-6477-BD, C1BY-6477-BE (2041312, 1785385, 5897251). Installation is plug & play – all mounting points are retained exactly like the stock flywheel, requiring no adapter or modifications.
What does the flywheel weigh and how much lighter is it than the factory unit?
The PMC Clutch flywheel weighs 5.71 kg / 12.59 lbs, whereas the factory flywheel weighs 11.33 kg / 24.98 lbs. This represents a 50% weight reduction, removing over 5.6 kg of rotational mass directly from the crankshaft.
Which clutch fits the PMC flywheel?
The flywheel works with the factory 228 mm / 8.98" Ford clutch: OE pressure plate C1BY-7563-BD and OE friction disc C1BY-7550-BC (OE kits C1BY-7540-BC, C1BY-7540-BD, 2031167, 1780138). Any aftermarket or custom clutch matching OE mounting points can also be used – example kits include Sachs 3000 951 550, Sachs Performance 3000 951 550-S, and LuK 623 3744 09 / 623 3744 33.
Is this flywheel suitable for daily driving?
Yes. A lightweight single-mass flywheel paired with an OE-spec clutch can easily be driven daily, delivering significantly crisper throttle response. Note that a single-mass flywheel may increase transmission noise transfer, as detailed in the note below.
Are bolts included and what is the torque specification?
Yes, crankshaft bolts are included in the kit. They must be torqued to 80 Nm / 59 lb⋅ft with threadlocker applied. Pressure plate mounting bolts and washers are also included.
Does a lightweight flywheel increase transmission gear chatter?
A single-mass flywheel eliminates factory dual-mass damping elements, meaning gearbox mechanical operation may become more audible, especially at idle. This is a natural characteristic of a direct, rigid engine-to-transmission coupling, common and desirable in motorsport, and does not indicate a defect.
What is included in the package?
The package contains the aluminum flywheel with a replaceable steel friction plate and zinc-plated starter ring gear, crankshaft bolts, pressure plate mounting bolts, and washers. Clutch pressure plate and clutch disc are not included with this product.
Does the price include customs duties for shipping outside the European Union?
No. The product price and shipping quote do not include customs duties or additional import taxes that may apply in the recipient's country.
Can I purchase with 0% VAT?
Yes, if you are a B2B customer outside Poland with an active EU VAT number (validated in the VIES system), or if your order is being exported outside the EU.
Please note that a lightweight single-mass flywheel provides uncompromising throttle response at the expense of factory damping elements. This results in a more direct drivetrain engagement, which naturally may increase audible gearbox chatter/gear rollover noise. This is an intended and normal characteristic in motorsport vehicles resulting from the rigid mechanical connection between the engine and drivetrain.
