I agree, I ordered the chrome since the LTZ has so much added chrome pieces, and I wasn't planning on changing it all. Just need to figure out which tires to get. Sounds like everyone likes the Nitto's compared to theFalkens.
I have a white Diamond Tri-coat Ltz, personally i dont think black rims would look the best on a white or WDT LTZ since they have so much factory chrome unless you were to paint everything including door handles white to match and do either black or white bowties. Kind of like "Rob Dyrdek's" from fantasy factory. Just my 2 cents. Do what feels and looks right to you bro.
