6'2", 190#, 36" inseam (you guys have short legs)
I can barely put a flat hand above my head in sport seats. No room for a helmet. Would like to sit a lot lower. I have gt3 seats but don't know that I can live w/ them as a daily (no padding is fine - the side bolsters and no back seat access are tough). Looking for 997 sport seats as a possible compromise. Also contemplating a sunroof delete.

 

Buddy of mine is 6'8". He seems to have no problems. I believe he has the sunroof delete, which gives a bit more headroom.

 

buy a carbio =)

 

I'm 6'4 250 and fit very nicely in my 996 Turbo, and was about 275 when I had my 996 C4. The only other sports car I've driven that I fit so comfortably in was..... nothing. Cramped in a Ferrari, forget about any of the Japanese stuff, American muscle yeah you fit but I like German engineering. I wouldn't have any concerns at your size.
