Not sure how it will look with 22" up front and 18" rear. I've seen 20" front with 18" in the back and I think it looks good with a nice fat drag radail.
With your HP level and 22" tire/wheel setup, it's got to be tuff getting a good jump off the line on the street.
I think a 19" front with 18" rear would be a great street/track combination setup.
Here's a rear view of my car with 18" F14s with 305/45/18 Drag Radials. Most cars give me a lot of respect on the street just because of my rear tire setup.
