What offset do I need for a flush or close to flush fit??

I've read wildly different numbers. Some guys are saying a +30 for the front will be flush and others are flush at +20. By my rough calculations, it should be closer to +20. For the rears, I figure about a +16??

The only problem with the fronts is that the semi-concave only goes to +26. The don't have anything lower than that. So should I go deep concave in the front and super deep for the rear? Or just stick with +26 in the semi-concave and it should be ok for the front and deep for the rear at +16? Or if I go with 18x9 in the fronts, what offset do I need? Something around a +28?

Help me decide!

For reference, most guys with Volk GTS wheels are running 19x9.5 +17 and 19x10.5 +18. TE37 owners with the same wheel widths and diameters as mentioned, however, run +22 front and +12 rear. For your Forgestar 18x9.5 front and 18x10 rears, I would get between +22 and +15 front, and maybe something as low as +6 in the rear since you intend on running 18x10 wheels.
