custom wheel sizing

front
17x8.0 w/ 225/45/17 rubber
rear
17x9.0 w/ 255/40/17 rubber
My first thought is to just use the standard 35 offset that I have been using, but obviously there could be disadvantages to this. Is there a good way to measure things once the wheels are off and figure out the geometry? I'm thinking about making a cardboard mock-up of the wheel along with a movable center where I can test various offsets for clearance. The main problem that I see is finding wheel well clearance when the struts are fully loaded. Thoughts? Thanks guys!
