I'd prefer 19's on the SS, but I don't think the brakes allow for that.

Yes it is. The bigger the wheel, even if it is a bit lighter, has more inertia. A 10% increase in diameter means that the rim would have to weigh 18% less in order for it to not lose straight line performance. It becomes less responsive to acceleration and to braking. This is why it is always recomended to upgrade the brakes when larger wheels are used. Additionally, the smaller sidewalls have less flex but again, that hurts acceleration. Not to mention durability, a pothole at low speed with rubber band tires can damage those expensive rims. I'm also not too sure about the comment about being able to use the suspension better than the factory. GM tuned the suspension on the SS to the 20" wheels. So unless you tweak it to allow for the different weight, handling might be worse than before.
Note, if I've gotten any facts wrong in the above, just ignore any points I made with them
