Yeah this thread totally got jacked.
6'4" in a MS3! I'm 5'8" and still can't completely find the most comfortable position for me.
from what i hear, people about your height actually have more trouble with the proximity of the plastic to the right of the gas pedal. i've learned to drive this car with my seat further forward than any other manual i've had, in part so that i wouldnt have to move up if i have people behind me, but mostly because with the long clutch travel my release point is now more similar to where it was in my old car. i honestly have no problems being my height in this car... im used to much smaller, but this offers plenty of leg room and head room, both of which were lacking in my last ride.
