Solved

I don't run fast enough; Help.

I try to improve equipment and everything, but I'm missing ... I do not get results.

My main suspicion is that I do not do the setups well.
Should we pay attention to what the pilots say and that the setup is the one they prefer or simply see what configuration makes the best return?

For the time being that.
A greeting.

What your driver says is perfect is the best setup.

Take a look at the Advnaced Guide at the top of this forum.

Hi there I’m new here and noticed is some tips page about spying on others teams but this was posted in 2017 is this feature still in the game 

Yes, it’s still in the game, but it’s now called “research” under the car tab. The help Page needs to be updated.

I read the full guide and it's very comlex. 

But it say that there is only setup each race, Regardless of the driver, car...

It's a little bit the opposite of what you told me. 

Please, can you clarify?

There is one each race, but for each driver alone, so both your drivers maybe have a different best set-up.
A long driver wants something different than a small one, just like in real life.
