I know that with stock type struts the tires will rub in the rear with anything over 205/45/16. Front is fine though. As far as height I'm not sure, but if you're already "slammed", then why go taller? You'd probably need to raise it some if you do. You're going to a total wheel/tire height of 20.035 inches from 19.632. 0.403 inches taller. I went from 205/45/16 to 215/50/16 with Hypercos, and ride height is still fine, but 5mm spacers were needed in rear.
