Here is my YZ-4 setup i have done a ton of testing with this buggy and this is what I have nailed down as my base setup for med bite dirt clay track that changes drastically through out the race day. It is super easy to drive and all I change as the track changes is sway bars. Thinner when its loose and thicker when traction comes around. I hope this can be some help!
