You guys with track time seldom mention two things that make a huge difference on how a car actually gets around corners:
1. How well the driver is seated/belted in
2. And the driver's skill/experience level

Those two items will likely outweigh almost any 3 things mentioned so far except maybe the tires, ie the driver needs seat time before going off on an internet induced spending sprees.

Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.
