Also typically on faster tracks we would change onto the higher Ackerman setup. like, yeah sure, on paper you'll be outright faster with less Ackerman but the inside wheel drag basically amounts to a built in left foot brake effect that stabilizes the car and is super benificial in tandem.

Maybe in some circles, but most pro s-chassis' are rocking lower caster than ever. Pretty sure Odi uses like 2*. Mechanical trail helps quite a bit. I ran 4* of caster and it felt like 5-6 when my power steering was working. I'm not sure what you mean by "fall to angle". Sure caster helps a lot of people steer, but a lot of people are still rocking cut n' shut knuckles. Kinda like bringing a club to a gun fight IMO.
The only cars I know of that actually use weight jacking are the Gittin and Denofa mustangs, and those dudes clearly steer with mostly throttle and don't have much front end grip in general. The cars also have a lot of anti-squat, which makes the combo drive the rear tires into the ground. Do that in a lowish S14 and all you'll do is drag ass and do a burnout.
If you're just trying to go super fast, then you can obviously rock higher static caster and ackerman, as lower steering angles mean their effects are less extreme. But if you're trying to rock deep angle and still have good braking and steering response at angle, then low caster and ackerman are where it's at.
Ultimately it comes down to your driving style and how you want your car to perform. A guy that drives for fun and goes to bashes and someone who wants to eventually run Formula D have different goals and require different setups.
Super low cars will clear the fenders better with higher caster.
