6S is fun! To fast for racing but so much fun once in a while. But I think my Badlands are gone, I don't get much grip from them anymore
I am trying new mud flaps I made from battery shrink

Battery shrink is tough, somewhat rigid and flexible and they are the thinnest, lightest mud flaps I have ever done. They seem to hold up very well, even with the front wheels flinging rocks on them on 6S.
