im 6'4" and i fit fine in my 95 2 door LS

 

6'1" here never had a problem in my ls 2 door except when (before I learned) not to leave you knee by the steering colum when closing the door lol its not at all fun when you smash your knee. just something to look out for but other then that youll be fine my cousin is 7' and has had no problems with his GSR.

 

Im 5'9'' and I love my Sedan! (not very comparable to you, I know)

 

6'4"..........99GS sedan........no problem with headroom or legroom.

 

yeah its all in how much you lay the seat down. If you're kinda person how likes to sit straight up then you might be out of luck.

 

Specs for a 2000 Integra GSR:

Front:
Head room: 38.9"
Leg room: 42.2"
Shoulder room: 52"
Hip room 50.7"

Rear:
Head room: 36"
Leg room: 32.7"
Shoulder room: 50.3"
Hip room: 49.9"

I'm about 5' 10" and have plenty of room. My buddy is about 6' and is very close to the ceiling. Don't even think about sitting upright in the rear. I can't even do that. I do have a sunroof.

FWIW
