Hardcharger,
Take your time in this decision.  If you want bling, do what you wish.  Low riders are usually exempt from high performance. If you want performance, I'd stick with the 18s and a better tire.  Remember, you'll be adding UNSPRUNG weight to the car by going to bigger, heavier, 20" rims.  I believe the tires are about the same weight.  What unsprung weight does is makes you slower in the straights and heavier in the corners, because the engine must do more work to spin those heavier wheels and in the corners you may need heavier springs, shocks, and sway bars to equal out the more mass (weight) in the corners. 

It is very difficult for most people to figure out that when you change something you also must change something else to equalize your change. 

Also, the lower the profile, the tire will FEEL great in a hard corner, UNTIL it just lets go and you're in the pucker brush -- the 18" tires are more forgiving (taller sidewall) and start to make noise before the lower profiles will, but will allow you to recover -- IF your not completely out of shape.

Also, the SRT8 tires are only about 1/2" wider than our stock '06 tires.  THAT isn't much of a performance change.

Choose wisely my son -- think about WHAT you want to do with the car before spending thousands of dollars and be disappointed.
