In general C16 is useful because it allows a lot more boost than pump fuel, and also is very safe as you are not walking the knife edge quite so much. With a good tune it would be fine I think, although only really worthwhile if you are making use of the benefits of such a high octane fuel. You would certainly need a different map from pump stuff.
I don't get what you mean by race o2 sensor? Leaded fuels will cut down the lifetime of an o2 sensor, if that's what you mean?
The only thing that I would do is keep an eye on the spark plugs as you may find it fouls them a bit, might depend on driving style and tune.
