I'll take some pictures of mine if you want. I'm using 255/35/18's on the front and rolled the fenders. (no understeer!) The rolling tool wouldn't clear the calipers and I was too lazy to remove them so the job isn't perfect but most don't notice the shortcut.

I removed my supercooler and went back to stock and my IAT's are more or less the same. I'm thinking perhaps my I/C pump is weak.
