I used a 275-40-17 on a WS6 firebird wheel and they fit great. My car is a Z-51 and there is no clearence issues with the brakes. The 17" wheel has more sidewall and the M/T drag radial in that size will provide plenty of traction, maybe too much.

Ok I could buy some OEM fronts, have the wheel widened so that it would have a 79 mm offset. I guess the wheel would be widened towards the inside offset by 23 mm. I think I would have them widened to 18x11 and run the 315 BFG DR's. Could I even go to a 85 mm offset with an 11 inch wheel??
I think this is possible, correct??
Now my only other concern would be will OEM fronts fit over the brake calipers on the rear of a Z51 coupe? Does anyone know or has anyone tried this to see if they fit?
I am trying to have my drag radials ready to go when my car gets here. I need to be very sure of the specs before I order or I could end up with some wheels that won't fit.
