…”hub to hub width”. Do you mean wheel base? If that’s the case, it’s listed on the owners manual and the website. I don’t know if you’re setting up for the 2 or the 5? Now if “hub to hub” you mean the actual width of the car, it’s 64” wide… minus 5” from the outside of both tires = 54” for the center of your front tires. The rear tires are 11”s so minus an additional half inch from each side. I hope it helps
