i made my own solid flywheel for the focus as though the valio one was shit.

i got a fly wheel from the earlyer tddi focus, welded up the timing marks and remachine in the new ones from the tdci (36 pick insted of 18)

then spaced out the realease bearing 2mm (this is important, you could change to an earlyer clutch arm insted if you prefered. )

its done 10,000 miles now and theres no difference in smoothness, runnng a remap and boost rise aswell, with a standard tddi clutch plate
