Hey this is my first time upsizing from my stock 2006 tC, and I've read TONS of info from multiple sources including the chart on this thread for offsets and nothing seems to be 100% clear to me because much of it is conflicting. So i was looking for any help concerning the look of my upsizing. My tC is completely stock 17" stock wheels, no drop etc., and I've been looking at these XXR 530's - 18x7.5 +38mm offset, OR 17x8.25 +35mm offset (i believe).

Questions are:
1. How will this look (flush/tuck/poke)? (I am going for 100% flush, or if anything a tiny tuck, i hate poke, its disgusting...)

2. Will anything rub?

3. Which size is better/ makes more sense? (I'm not planning on adding a drop kit anytime soon)

4. What should else should i be concerned about?
