Trying to get my head around bump / rebound and what a higher/lower vale means in AC.

Trying to get my head around bump / rebound and what a higher/lower values means in AC.

Going by AC's hints when highlighted, I imagine that increasing bump is lowering the dampening in bump, as opposed to increasing it. Have I got that correct ?

But then for fast bump, going by the hints, I imagine that increasing the value is increasing the dampening.

Have I got this all wrong ? Or is it really this unintuitive ? It is not just AC that is confusing me on this.

"Dampening" is to make something wet, "damping" reduces oscillation.

The descriptions are a bit confusing, but as far as I can tell, higher values equal higher damping in all cases.

The description for fast bump says, "Lower values make the suspension capable of absorbing more energy on bumps and kerbs but then you need to make sure it won't bounce down again upsetting the car."

Consider the statement, "lower values make the suspension capable of absorbing more energy". Now imagine a car with a low fast bump value driving over a high kerb. The suspension moves up quickly when the kerb is it, in such a way that the car's body glides over it. The suspension has "absorbed" the energy from the kerb without upsetting car.

Now imagine the same situation, but with a really high fast bump value. The damper is so stiff that the spring barely moves as the car hits the high kerb, absorbing nothing and launching the car into the air.

Thanks Hawk, what you say about fast bump was my line of thinking and easy for me to understand. I am having a bit of a hard time accepting that increasing values of bump is increasing damping though. It says something like "higher values make the car more reactive..."

I was thinking that more reactive would be when you had less damping.

Increase = Make it more stiffer.
If you increase the bump, the suspension will resist more to compression.
If you increase the rebound, the suspension will resist more to extend back (this can make the wheel lose contact to the ground).

"higher values make the car more reactive" because the car "roll less", but it lose grip also.
with lower values you can feel the car body rolling before the turns, it feels smooth and a bit unresponsive.
Try to find a good balance.

PS: This is the same in every game I played :D

Here are some tips:

Camber and toe will help you a lot too, specially in tracks with a lot of turns.

Sorry for my english :D

Thank you, I always looked for tyres temperatures vs compound.
