I'm 6'3" and I have an inch of clearance from the top of my head to the ceiling. My seat is slightly tilted back for comfort, but nothing like you see those little punk thug white wanna be kids practically laying in the back seat.
There was a guy (on one of these forums) that had cut his lower rails down an inch or so. He had access to the proper tools and knowledge of welding and cutting. There was write up somewhere on it. It turned out looking pretty good and he gained some head room. A definate 10 out of 10 on the difficulty scale, especially due to the fact that it's cutting up your seat rails. Those new welds better be damn good!!!
