I got a set of stock Avenger 17" steel wheels complete with nuts and covers ridiculously cheap, the only issue is that the center bore is too small. According to every reference I can find, the Avenger wheels have "high positive offset", exactly like that which is listed for the Intrepid wheels:
So, I don't believe clearing the caliper will be an issue (maybe, maybe not, I'm not near the vehicle so I haven't test fit them yet). As for 1" spacers being "too much", I see plenty of people running with 1.5" spacers and as far as I am aware, they aren't unsafe when installed properly. Since the Intrepid's lug studs *can* be changed without replacing the whole wheel bearing assembly (unlike my 02 Grand Caravan) I will install the spacers with locktite on the studs, and if I ever need to revert back to my other wheels I'll count on having to twist off the studs to remove them.
Anyone have an answer for the stud length question? I suppose I will just buy a set of standard length studs and cut them down otherwise, preserve my original studs (box in the trunk) and run with that. They're cheap at the auto parts store, like, a buck a pop so 20 of them won't break the bank.
