As you said, once it takes a set the stock suspension is actually pretty good. The real area where it's evident how soft it is would be during transition and the rapid side to side weight transfer that happens as a result. It's still manageable though.
You're right that on the street, except for the longest and steepest of high speed canyon descents taken at cuckoo speed, there should never be an issue with the stock brakes and the grip of the tires used will matter much more.
I don't see how upgrades will make things worse though unless racing pads that requires coming up to temp to be effective. That aside, by virture of their opposed piston design, the Brembos do tend to offer better modulation and feel. Hardly necessary for street but nor mandatory on an auto-x course, but nice to have.
BBKs adding unsprun weight at the wheels, or only upgrading front breaks upsetting the bias
