picture wise, the Z06 wheels look better just because the car is super clean, way better angle on the shot and looks like a possilbly better camera was used. Im sure with those items being the same, the ZR1 wheels would look just as good, especially now that you have a real grill but those red calipers need to go man, nothing else is red on the car except the outside edging of the SS emblems...thats not enough IMO. go with the silver/black thing since your car is pretty much all blacked-out and kill those silver center caps for sure, get black ones or at least sand those and paint um up too becuase they look tacky on the black car....again IMO. If you get black center caps, get black lug nuts too, they made a huge difference on how my ZR1 wheels looked on my white fbody, so much more nice to the eyes. You have a clean (when not dirty) SS, go with what you want, but I think a few adjustments need to be made and then the type of wheels you have on there wont even matter cuz the car will look good no matter what
edit: is that a white fbody in the reflection of your car in the first pic? near the front fender/wheel well?
