Front tire and rim size, Help.

I run 205/70-15 on my Dart Sport but they are on 7'' rims, since yours are on 6'' and 215, they would definitely be taller so you might ha to raise the front end a bit but if they don't rub you would be good to go.

Ok. How do you raise the front and rear anyway? I like the look of the rear raised a bit but not sure how to do it.
