Clutch Masters Aluminum Flywheel 17-20 Fiat 124 Spider 1.4T
The Clutch Masters FW-703-AL is a lightweight aluminum flywheel for the 2017-2020 Fiat 124 Spider and 124 Abarth with the 1.4L turbo and manual gearbox. Owners shopping for it are usually doing a clutch job anyway, because the disc is slipping, the flywheel face is scored or heat-checked, or the car is headed to autocross and track days, and want the engine to rev and settle faster between shifts. Unlike many conversion flywheels, Clutch Masters says this one can be used with the factory clutch kit as well as its own kits.
The flywheel bolts to the back of the crankshaft and gives the clutch disc its friction surface. Its mass also stores energy, which helps the car pull away smoothly but slows how quickly the engine can gain or shed rpm. On a light rear-drive roadster with a small turbo four, taking mass out of the flywheel is one of the most noticeable changes you can make: blips for heel-and-toe downshifts come up faster and revs fall quicker on upshifts. Clutch Masters CNC machines the FW-703-AL in the USA from 6061 aluminum, zero balances it, Type 3 hard anodizes it and certifies it to SFI 1.2 for motorsport use.
Most flywheel faults show up as clutch symptoms, so start there. Warm the car, select fourth around 2,000 rpm and apply full throttle on a safe road; if the tach rises ahead of speed, the disc is slipping. Our slipping diagnosis guide covers the test, and our manual repair cost guide helps you plan the labor. A pedal that will not release fully is usually hydraulic, so bleed and inspect the slave before ordering parts.
Clutch Masters lists FW-703-AL for the 2017-2020 Fiat 124 Spider 1.4L turbo, including the Abarth. It is for the manual transmission only. The 124 shares its body with the Mazda MX-5, but the Fiat engine uses its own flywheel, so a Miata flywheel is not a substitute and this part will not fit a Miata. Clutch Masters states it pairs with the OEM clutch kit or any of its FX100 to FX500 single-disc kits; from our catalog that means the FX100 kit 05703-HD00 for stock to mild cars or the FX250 dual-friction kit for tuned cars.

Replace the flywheel during the clutch job so the new disc beds against a flat, fresh surface. With the transmission out, clean the crankshaft flange and threads and check the rear main seal; any oil weep has to be fixed now or it will contaminate the disc. Install with new bolts, the thread locker and torque given in the instructions, tightening in a cross pattern. Wipe the friction face with brake cleaner, center the disc with an alignment tool such as the Powerbuilt 8-piece pilot tool set, and tighten the pressure plate evenly. Bleed the clutch hydraulics with the fluid named on the reservoir cap, then follow the Clutch Masters break-in before hard driving. A lighter flywheel can add some gear rattle at idle and needs a touch more throttle on takeoff.

Yes. Clutch Masters lists the 2017-2020 Fiat 124 Spider and Abarth with the 1.4L turbo.
No. The 124 Spider uses the Fiat 1.4L turbo engine, which needs its own flywheel. Use a flywheel listed for your Miata engine.
Clutch Masters lists a shipping weight of 13 lb with packaging.
It works, but takeoffs need slightly more throttle and you may hear more gear rattle at idle. Clutch Masters generally recommends steel for mostly street use and aluminum for performance driving.
Replace the disc, pressure plate and release bearing, check the rear main seal, and use new flywheel bolts.
