18x10 irocs or 18x9

Hey guys, I get the feeling this question may have been asked before, but doing a search didn't bring it up.

I'm gonna buy the 18x8 iroc rims, but I'm going to have them widened.
I don't know if I should widen them to 18x9 or 18x10.

Can they be widened to 18x10 without clearance issues??

Depends what the origional offset is. It should work with some typical hammering in places.

Well, most companies use the front offset on all four wheels. I believe it's 0mm. But I'm concerned if an 18x10 widened iroc would fit in the stock wheelwell even with spacers.
