okay..
its true cordia's have a smaller flywheel
the only way for a cordia owner to use this flywheel and also use a vr4 / evo / gsr clutch pressure plate and disc is to upgrade the gearbox..
this is done by using a FWD sonata gearbox like explained in the 4g61t document..
so if anybody is interested in doing the swap over..
my flywheel is for sale =)
