clutch on my TT, its significantly stiffer then my stock one and thats with a booster, so i can only imagine one without the booster. I was making the assumption because i drove a NA with a Sport clutch on a NA and it was stiffer then the stock clutch on a TT, so i was thinking a TT clutch on a NA must be alot harder since the pressure plate is made to hold torque of a TT engine.
