3rd Gen Nova Wheel Advice

[neltner_nova]

I'm hoping to hear from some 3rd gen owners on what kind of wheel setups they're running. I'm doing stock suspension, or at most a 1" drop front and back; no tubs or flares. I'd like to run 17 or 18's without modifying the suspension or body. What type of offsets, back spacing and widths do you all run?
