Sounds like a smart move. I did a little autox before lowering the seat, but it is better to have a good fit and a requirement for the track. Everyone is shaped different, but I am a little of 6'4" and can now wear my helmet without hitting the padding in my hard top. Good luck with it.Sounds like fun but that's one of the reasons I am interested in the tall rails. I'm 6'2" and barely fit without a helmet. I know I could run without the top on but with just the factory 3 point seat belt that's a lot of travel above the top of the car I could do if something goes wrong.
