they look ok. i like 7 spoke rims.

have you checked out konig heliums? those are nice... i was about to pick up a set of those until i found some racing harts at a killer price.

as for rubbing issues. if you go 18, go with 225/40/18 tires. my friend has a AV6 and he's got the same size tires as i do and we both dont have any rubbing issues.
