SPEC part number SF333H-9 is the Stage 2 Plus clutch for the turbocharged 1.6L Ford Fiesta ST. Stage 2+ is SPEC's multi-friction disc: SPEC describes it as maintaining the excellent drivability of their Kevlar Stage 2 disc while carrying 15-20% higher torque capacity, and rates this specific part number at 331 lb-ft.
That number matters on a Fiesta ST, where a stage-2 tune comfortably clears the stock clutch's grip long before anything else in the driveline complains. No flywheel is included in this kit and SPEC does not list one as required for the Fiesta ST application. SPEC's published coverage for SF333H-9 runs 2012 through 2019, which is wider than the 2013-2014 window this listing previously showed. Torque capacity rated by SPEC at 331 lb-ft. SPEC rates Stage 2+ for street, drag, pulling and autocross use.
