First off is the mother of all hub sizes and bolt pattern lists. Don't get discouraged if the wheels you're looking at don't have the same hub bore as our cars. They can still fit. If the wheel's bore is too big, you can use hub-centric rings. If the bore is too small, you can send the wheels to a machine shop and have them bored out.

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.

Very nice thread Aaron! There's a lot to consider when selecting the right wheel/tire combination for your car. I sometimes wonder when someone comments "those wheels really fill out the wheel well" know it's generally an optical illusion. For instance, if you increase your wheel size from 16" to 17", the profile of the tire changes to maintain the same rotational diameter. So while the wheel gets taller, the sidewall grows smaller. Of course, you can go to a taller wheel and tire profile, however than you need to make adjustments in the speedo/odometer calibration settings to compensate for the decreased revolutions.

Nice info Aaron. I am going to move this to the DIY - General Info section if thats ok. oh and + rep added to you for the contribution.
