Does it make a difference if I go with...........
I currently have a 2013 C6 Grand Sport I'm currently getting new Black wheels I have the Chrome wheel stock size front 18x9.5 rear 19x12. Do it make a difference if I go with replica Zr1 Front18x9.5 Rear19x12 or Front 19x10 rear 20x12 or Rear 19x12 rear 19x10 sqaure set up. Is any better or worse. I'm not tracking the car or nothing just street riding & cruising thanks for any advice in advance

Ratio of front to rear tire diameter matters. If you go too far out of stock specs, the nannies will assume one set of wheels is skidding or slipping, and take corrective measures. The effect is likely to be more pronounced the faster you go.

Are the current tires in good shape? Or you're planning on buying new black wheels and new tires? If you're going to buy new tires w/ the new black wheels, I'd move up to a 19"F / 20"R set up. To me it just looks better.

I'm getting new rears the fronts are new that's why I'm thinking about same set up. But like you said the 20s & 19s look better but will I sacrifice ride quality or have problems going bigger

19s and 20s will ride worse due to less sidewall. They also look worse because your brakes them look small. IMO, 18s and 19s, or 18s and 18s works best on the c6.

But that's my opinion.

Increasing tire diameter will mean calibrating the speedometer. It will only be off by a couple of miles per hour, but it effects other things as well. Such as your average and instant fuel mpg reading, and other things.
If you go bigger watch the width. You don't want the tires rubbing the fenders, it looks terrible and damaged both. Tire rack has a calculator to keep everything in-line if you go with bigger wheels.
Final opinion, as already stated above bigger wheel and keeping tire size in-line will mean smaller sidewalls and rougher ride.
