Clutch Masters 17-20 Fiat 124 Spider 1.4T FX350 Sprung Fiber Friction Lined Disc Clutch Kit
The Clutch Masters FX350 (part 05703-HDFF) is for the 2017-2020 Fiat 124 Spider and 124 Spider Abarth owner whose 1.4L MultiAir turbo now makes more torque than the stock clutch can hold. A tune, a larger intercooler or a bigger turbo pushes the factory disc past its limit quickly, and the first sign is usually slip in third or fourth gear as boost comes in. This kit raises holding capacity well above stock while staying usable on the street.
The 124 Spider is built by Mazda alongside the ND MX-5, but it carries Fiat's 1.4L turbo engine, rated at 160 hp and 184 lb-ft in North American form (164 hp for the Abarth). Fiat paired it with the six-speed manual from the previous-generation NC Miata to cope with the turbo's torque, so the clutch is not shared with the ND Miata. Boost arrives low in the rev range, which loads the clutch hard right where a worn or stock disc gives up.
Clutch Masters rates the FX350 system at a 110 percent increase in holding capacity over stock. It uses their Power Plus I high-leverage, heavy-duty pressure plate with a steel-backed, segmented Fiber-Tough disc on a sprung hub with a marcel spring. Clutch Masters positions it for the serious street driver who also runs track days, with a highly tuned or medium-boost engine. They are open about the trade-off: engagement is slightly more aggressive than their FX300 and it will produce some chatter.
Boost problems can feel like slip, so check that the car is actually making its target boost and look at the tach against road speed in a high gear at full throttle. If rpm rises without matching acceleration, the clutch is slipping. Our slipping diagnosis guide covers the test, and shift flare vs slip helps separate a real slip from a momentary flare. Also check the hydraulic fluid and slave cylinder, since a soft pedal causes grinding and drag that a new clutch will not fix.
Clutch Masters lists 05703-HDFF for the Fiat 124 Spider 1.4L Turbo, 2017-2020, which matches our listing. That covers the manual-transmission cars sold in North America, including the Abarth. It does not fit an automatic 124 or any Mazda MX-5, even though the bodies are related. If the car has had a transmission or engine swap, or you are unsure of anything, send us the year and VIN before ordering. Lighter-duty choices for the same car are the FX100 kit for stock or lightly modified cars and the FX250 kit for moderate power with smoother engagement.

Yes. Clutch Masters lists 05703-HDFF for the 2017-2020 Fiat 124 Spider 1.4L Turbo with the manual transmission, which includes the Abarth.
No. The 124 uses Fiat's 1.4L turbo and the NC-generation six-speed, so the clutch is different from the ND MX-5.
Clutch Masters rates the FX350 at a 110 percent increase in holding capacity over the factory clutch, aimed at tuned and medium-boost cars.
Some chatter is normal. Clutch Masters says the FX350 engages slightly more aggressively than their FX300 and will produce some chatter. For a smoother street car, the FX100 or FX250 are better choices.
The kit does not include one. Resurface the stock flywheel or replace it; the FW-703-AL aluminum flywheel is listed for the same car.
