Good day!

I just bought an sc10 2wd last sunday and have been busy fixing all the things wrong with it. I am going to a my first off road race this weekend and would like some help with gearing. The motor is a castle 4600 4 polel and the speedo is a mamba max pro and it has a ball diff. The spur is an 81 tooth. The track was started to be put down today so the surface is anyones guess. Here is the layout of the track.
