Going 2 sizes smaller on the SRT, thoughts?

Did you go wider than 7"? I have to decide on 7 or 8". I suppose I have plenty of time until I need to get the wheels, but I want to make sure I do the right decision. I’m going to be running a slick at the track, so the wheel won’t be for cutting 1.7’s, it will just be for getting good traction on the street, with the use of some drag radials.

With my gear dependent boost, I should be fine with a 7" wheel…
