You can try adjusting the default.rfm file
We use the default.rfm file from the unpacked track (however most default.rfm files look the same to me).
Unpack track, add this line
DefaultScoring
{
RacePitKPH = 100
NormalPitKPH = 100
FormationSpeedKPH = 200
Practice1Day = Friday
and save it somewhere. You can use any speed you like, we use 200 km/h for F1
When making a new Mod Package, click the Customize box and select your adjusted default.rfm file and you are good to go.
I just use the same default.rfm file on every Mod Package (correct me if I am wrong, they all look the same).
