So looking through the good ol local craigslist... Found these.
Motegi Racing 18"
http://austin.craigslist.org/pts/515340584.html

I sent the seller an email but can anyone tell if these would fit on my 06 i4?

Sounds like a good deal but please let me know if buying these would be a mistake? sucks because I'm leaving for vacation soon tomorrow.. I might just have to bail on them.

It says 5 lug, but doesn't say what the bolt pattern or offset is, so :dunno:

Suggest you call the guy at the # listed
