So you could certainly go with potentiometers, but it would give you slightly different data. Ideally, you would want both for suspension and aero tuning.

Not much on the splitter. It does affect overall drag though. Trends are still valid for A to B tests. Drag will be higher when you have any sort of heat exchanger added to the mix.

Going stiffer is our recommendation. Give some mechanical grip up for more aero grip. It will also have a sort of grind plate at the bottom to keep it from eating itself

If we did carbon, it would be a full carbon upright. Sadly, this market wouldn't pay for the increase this would cause. Two carbon uprights with tooling would add a significant amount to our cost.

The wing was developed in CFD on and off the car to make sure we hit maxiumum efficiency. That is how we were able to have a wing that will produce 11.5 lbs of downforce for every 1 lb of drag.

This is true.

That area of the car is always higher pressure. I am sure there is a way to make it low pressure, but in general, that area is a terrible choice for evacuating air.

If I were to guess, I bet the factory spoiler reduces some drag, but very minimal. However, minimal drag decreases are noticeable if driving a lot.
