Anyone using 8X15" Ralley rims on all four corners?

[b5blue]

  I'm thinking ahead on rims and tires. I'd like all four the same wheel and tire like Tan Top's 8x15" with 255/60/15 tires. (With a matched spare in the trunk.) However his stock style rims come with 4" backspace and the Ralley style I like best shows only a 4.5 backspace. I have studied the wheels topic but it's so varied I thought I'd just ask here.
  So any input on 15' Ralley wheel/tire setups could help me nail it down with a focus on what's on the front and fits.
