I just had the conversation about seat fitment and according to Steve Wilkinson, the seat base width is limited to around 19" on the passenger side and 20" on the driver side. That limit is for the very bottom of the seat. I have Gary Herrings Corvette seats and love them. However, I have a set of cut down in height Ford GT seats I am going to go with. Only reason is the weight savings since they are real carbon fiber based.
