No, not a heavy clutch, coming from Mustangs, this clutch is much lighter, I think it's even lighter feel then my Mini Cooper S. My biggest complaint is that it's noisy, you can search for vids on here regarding that. Seams to be part of the design from what I've researched, so not too concerned about it. No mechanical problems and I just past 11K miles.
Drive both before you buy, but Syncro Rev match is awesome in the MT6.
