I'm 5 10 but have a pretty long torso so I sit kinda high in the car, really lean the seat back to fit. It seems my leg is at an odd angle to reach around the steering wheel for the gas pedal/heel toe and I always have to use my groin muscles to hold it the right way. So that is kinda annoying.

You can cut some padding out of the bottom of the seat to lower your seating position, plus that will put you lower in the wings of the seat for lateral support. I'm hoping that helps, but I plan on switching to a Spec Miata or Kirkley seat soon anyway for my 6 point.
