A LOT to be said about Anti-Dive and Anti-Squat too (touched on in the video).
As I recall the SpeedLab Corvette - has Zero Anti-dive/Zero Anti-Squat.
I like the idea of the forces through the CG. It would be an interesting ride.

I can see where removing what little dive there is under braking/on turn in would make it somewhat more difficult for the driver. But I'm not sure how that relates to tire front tire wear.
Is most front tire wear is due to braking into corners or going through the corner? Also, must of what I was seeing in these YT videos about McLaren, was related to brake temperatures. How do the deceleration forces change unless you are proportioning more braking to the rear tires (probably not a great idea).

I think he mentions the reason why keeping downforce constant from the underbody wing helps keep tires cooler.
When the downforce changes suddenly, the traction forces change rapidly, loading and unloading tires. The sudden changes in load is responsible for wear and heat, I believe is what he reasoned.
Pretty amazing that so many people are studying this to try and figure out their secret.

I don't understand how the brakes run cooler because of anti dive. The total (all 4 wheels) of rotational/frictional forces acting on the brakes that slow a mass of X from 200mph to 100mph are the same regardless of weight transfer. The only way to deploy and incredible amount of drag (think a parachute)b or transfer braking forces from front to back. That sounds like a very bad idea.

If you have less downforce your wheels have less traction, I’m thinking more pedal pressure (clamping force) to achieve the same braking force.
Second, if you have lots of traction, you are less likely to need brakes.
Third, unloading and loading the tires suddenly due to big changes in downforce, would also translate to big brake force changes. Those big spikes would cause temps to spike.
Just throwing out some guesses. Probably other factors.
