The range is hypothetical anyway. On my car, the max of the stock range on the front is -1.4. Most folks can't get the alignment to much past -1.0 without camber plates or the Turner washer kit (or with the car lowered). Bottom line there's no way to know how much you have to work with until you have it aligned.

My advice? First, get it aligned, ask them to max out the negative camber up front and keep it even side to side, and then consider what you want to do from there. Second, consider what the stock offsets are, and what your current offsets are (if not stock wheels) before selecting spacers. Changing from the stock offsets can have a very real adverse impact on handling due to how it changes the scrub radius. The Hack does a great job of explaining scrub radius in this thread, and why it matters (my summary of the discussion is in post 19 FWIW).
Gotcha! Thanks for the advice. I read up on that thread regarding scrub radius. I gotta tell ya, after reading about scrub radius, makes me not want to put on spacers and get tires that are bigger than stock.
