Does anyone know what offset would be used? I noticed that there was a 0, 24, and 45 offset. I would think that the 0 would work fine on the rear, but what about the fronts with disc brakes? I priced out 6 wheels (four with 0, two with 24) for giggles and it came to a bit over $600 to my door. That does not seem unreasonable for six wheels. But $450 sounds better.
