I'm 6'4" with the same inseam as you and yes, it is tight in there. My left knee hits agains the door and my right rubs on the dash. I did, however, fill the foot well to bring it up to the same level as the rest of the floor just to change the angle of my foot when on the gas peddle. Another couple of inches of room would be nice, so I will try raising and moving the seat back a bit. I'll also try changing the angle of the seatback to get just a little extra room. For now, I've adjusted.
