Scud/16M fronts are 8 inches wide, but I see a lot of Scud type wheels advertised that are 7.5. The 7.5's seem easier to come by. I'm looking for a second set of wheels for the track on the 16M. Should I really try to find another set of 8's for the front? I'm just trying to understand the pros/cons of the two setups. If I end up with one set of 7.5 and one set with 8, which setup for the track? I am assuming I would use the 7.5 with 235/35/19 for street with 285's on the rear. Then use 255/30/19 on the 8's for the track and go with a 305's on the rear for better balance. Any other suggestions?
