Wheel upgrade for 05 S

Does anyone know what the backspace should be for a steel wheel if I go to a 16x8 on my 4x4 S?

Your not going to get a steel wheel to clear the calipar without a wheel spacer. I believe there is a guy running 16x8 steel wheels with 5" BS and 1' wheel spacers.

EDIT: Unless you go with the OEM steel wheels from the dealership. These will fit with no spacers, and will be correct BS.
