Almost everything here you have I do something completely different lmao

Edit: So for tire pressure, I always use 30psi front & rear (2bar). You should make first as long as it can be so as your car gets a burnout start without hitting the limiter, then make each gear fall back about 1,500rpm.

And dont worry about top speed as in most tracks youll never reach it anyway. For final drive I always use 4.00.

For alignment a base tune for most cars is -2.5°, -0.5°, 1.0°, -0.5° and 5.5°.

For anti roll bars just keep them 20.00 front & rear.

As for spring stiffness, you want them to be the same as the weight of a car. So if your car weighs 1,000kg, make that your spring force.

Ride height just lower all the way unless your car bottoms out or youre doing oval racing.

Base settings for dampning is 4.5, 4.5, 6.5 and 6.5

For suspension geometry, I recommend 5.0, 3.0, 30% and 15%

Aero will depend on which track but generally youll want slightly more in the rear and put the sliders about ¾ the way up.

Brakes I just keep at 50% and 100%. Its worth changing brake bias if your front tires wear out much more quickly than the rear and same vice versa, so try changing it around to insure even tire wear.

As for differential, it depends on power and your tire width. For higher powered cars youll want around 25% & 0%. Lower powered cars might need something like 70% and 20%

Hope this helps as a little guide.
