groove_multiplier = 1
wet_multiplier = 1
1 is the default value. Increase it ( up to 20 ) to have the tires generate groove and dry the track faster. Please note that this affects tires only: the global track surface will still dry at the same ( slow ) rate.
Testing session only.

deformation_multiplier = 1
