The Clutch Masters FX350 high-rev sprung clutch kit for 2012–2013 Honda Civic Si 2.4L 6-speed is supplied with a steel flywheel and is built to work exclusively with Clutch Masters' flywheel; it will not function with the OEM flywheel. The FX350 offers increased holding capacity and a more assertive engagement profile suited for high-revving street and track use where a dedicated conversion flywheel is part of the installation.
