18" wheel offsets
 

I have an 03' base model CTS, and am looking at new wheels for it. I was wondering what the max/min offsets are for this model, as i'm tired of the curb rash on my stock wheels (spokes stick out further than the rubber). Can I even get a dish on this particular car?

TIA,

Ross

Yeah you can get it but its a little difficult to fin it.A better option to deal with a automotive parts seller or you can search it online on eBay and then if it is compatible with your car so you can put it.
