The Clutch Masters FX350 clutch kit for 2014–2018 Mazda3 2.5L is a sprung-disc kit specified to work only with a single-mass flywheel built to OEM specifications. It is presented as a higher-capacity single-disc clutch option that requires a single-mass flywheel and will not function with dual-mass flywheel setups. The kit targets applications needing a direct-fit replacement within those constraints.
