Mustang Bullitt Wheels
After crunching some numbers I don't think that the 18 x 9 will fit under the HHR right. It may work but it does not mean that it is right. 
I might have to go with the 17 x 8 but I have almost brand new 18" tires and Solstice wheels.

I sold rims and tires for 9 years and I have never seen or heard of a 18x9 working on a true FWD car. Yes Mustangs and Camaro have Hi offsets but they are RWD and can get away with some fitment issues. But I really don't think a 9 inch wheel with a 30 mm offset will fit or or even look right. It will stick out of the fender and be tripping people as you drive down the road. The original fitment was a 17x6.5 with a 42 mm offset and it was flush with the fender. I don't know but I don't want to spend $700.00 on something that I don't think will work in the first place.
