I'm 6'8" and I've found that I don't come close to fitting in either TT's or Na's. the T-tops don't help either because when the seat is all the way back my head is behind the opening. its unfortunate that Nissan decided not to spare an inch when they designed this car. Has anyone had experience with after market seats that might provide more head/leg room? I've heard that all-out racing seats that bolt straight to the floor might do the trick, but the sacrifice in comfort would just be too much.
