So how can i get the ideal result for wet race?
Once you have found the correct settings for a circuit they will be the same every time you race there as long as you use the same driver. So make a note of the settings somewhere.
If you use a taller driver next time you race at the circuit the ideal ride height will be lower and if the diver is shorter he/she will ask for a larger ride height.
There are two levels of rain, normal and heavy. Normal rain is the most common. Heavy rain is usually snow so tends to happen when it is very cold (Europe in the winter).
For both types of rain the suspension stiffness is the same as a dry race.
For normal rain you need to add to the dry ride height and wing:
Rookie: Approx. 6
Pro: Approx. 12
Elite: Approx. 25
For heavy rain you need to add to the dry ride height and wing:
Rookie: Approx. 12
Pro: Approx. 25
Elite: Approx. 50
These will get you within 2 points of the ideal setup, you may need to do a couple of laps to tweak them if they are not exact.
