Front Rubbing - Tires, Suspension or Wheels?

Another question. Is there any difference in looks between the one and two piece versions of the TTII? If they look the same and I can get away with a 4.0 bs on the front as opposed to a 3.5 then I can save a significant amount with a one piece wheel. The difference just at Summit is $56. I could knock off another $59 each through Amazon. That would save me $230. I think I'm stuck with the two piece for the rear.
