I was wondering which one everyone would think would look nicer on a CTS... I like both... they both come in 18 inch.... however the Diablo can come in a size 19 while Donz you would have to go wit 20's....

The first one is the Donz Corelone and the second is the Diablo Lionhart :

Diablo in 18s would look nice.:coolgleam

Go with the Diablo's the Donz are way to gaudy and Donz wheels are way over priced for the quality wheel that they are, Diablo has a little better of a track record and are more established of a wheel manufacturer.

I have the black 18" Diablo Lionharts on my black '04 CTS. I really like the look.

Both are too busy for my taste, but if you must, go with the reputable manufacturer.
