I am 6'2 200 pounds and I could not drive the SPF with a helmet on. Maybe not even without the helmet. The RCR has a lot more room. Check out
www.gt40s.com There is a lot of info to go through. I suggest you sit in the cars before you put a deposit down. Ther is a picture of my new RCR as a deluxe kit in my gallery. I has not been delivered yet but I am very excited.
