Honestly there should be some sort of lift kit for a HHR just for the fact of look at all the stupid cars out there that have 36" rims think about it in order for them to be able to do that they have to put a lift kit on them so my guess would be go to a place that specializes in that and see if they can come up with one thats what I plan on doing with my wifes 07 HHR bc I want to lift it 3 inches nothing more and I will probably place a set of 1.5" wheel spacers on it to eliminate the tire hitting the strut issue bc I want to put a set of A/T on it

 

i saw a picture once of where they placed the body of the HHR on a 4x4 S10?

 

put a HHR on a 4x4 s10 frame that's a lil extreme and take the fun out of it also now I once took a 81 cutlass supreme and placed it on a single cab short wheel base Z71 with a set of 44" super swampers under it and placed across the back if your going to lift it lift it for a reason I got harassed all the time by the idiots that lift them just for those big ass ugly wheels but pissing them off was the meaning behind it in the first place but was a fun mud toy thinking about doing a caddy next for them lol
