Next is a wheel offset calculator. Use this to get an idea of inner and outer wheel clearances. The offset number is measured from the center of the wheel width. Thus, a 35mm offset on a 6" wide wheel is totally different than a 35mm offset on an 8" wide wheel. For reference, stock wheels are 6.5" wide and have around a 52mm offset. Not positive on that, but it's within 2 or 3mm of that.

Last but not least is a tire size calculator. Stock size is 225/60/16. Use this to get an idea of what your new tires will look like in comparison to the stock ones, and/or to match the new size as closely as possible with the stock diameter/circumference.

Other useful info I have for Regals/w-bodies:
Offset Range: 34 to 45
Wheel Size Range: 16x7.0 to 20x8.5
However, I'm not sure how reliable the offset and size range info is, because stock wheels are actually 6.5" wide, and I've definitely seen guys run 9" and wider wheels before. So, take it with a grain of salt. Still gives you a decent idea.
