G6 wheels are 5x110 though I'm pretty sure.

 

Yeah the G6 have the same bolt pattern as our HHR

 

Well i know they are Im jus saying make sure they are 5x110 jeez guys, I like to think im not new to the HHR game.

 

ya' 5x110 are fine. just watch for the offset of 42(SS anyways). Sometimes GM thinks that if a different offset doesn't relate to their specs, they may not warranty a part that is suspension affected should a part fail. Depends on your dealer, some say it will be ok, some not. IMHO.
