BUT, and i'm sure you know this already, going from a 8.0 et47 to a 9.5 et35 will definitely alter the SR. i understand you plan on lowering the car, and you'll need to add neg camber... and HACK is probably better at explaining this than i... you'll have a positive scrub radius of ~ 31mm, which is not great for cars like ours with a macpherson system. but you'll have boat-loads of grip!!

here's my favorite resource for info on SR..

Right that was my point, since diameter doesn't apply, you could probably take Paintpro's findings and apply it here. I think of the 3 setups he tested, he showed at least 1 that would fit w/o the need for camber up front.
