Hey guys, I saw a thread about some Corbeau Forza Sport seats and the thread was a bit old and they didn't specify if they bought the 20.5 or the 21.5 seat size. Anyone know if the 21.5 seat size will work? Also new to buying racing seats, do I have to factor in a rollbar (5 point) ? Also if you have any rec. for big seats for big dudes please feel free to post (Yes I have used the search button and yes I'm trying to lose weight). Thanks guys!
