I am only 5'5 and weigh about 170 lb. I feel like my driver's seat is so tight that I would really much rather have a wider seat or at least the big wings sticking up could be adjusted outwards a little bit. I can't even imagine how people who weigh more than me, can be comfortable over a long period of time. Does anybody have any insight or how this can be adjusted or are most model X drivers just putting up with it?
