About what you said first, if you use MWN the tracks should work. Are you sure the tracks you installed are supporting 2.2.1 MWN? About scripting, I know the basics, but I can't help with that one. About the second question, do you mean drag racing in Valo City it drag racing on Miran's drag strip mod? If you meant the drag strip, I might be able to help. If not, I am not sure if it's possible. You can always ask the experts, I am especially a 2.3.1 expert so this is not something I have too much knowledge about.
