Well I ran mine at the track tonight, after over 2 hours of hard running the only thing that happened was both mud flaps disappeared. I have the Novak Havoc 8.5 set up in it and it is definitely to much power but man what fun. I put the rear outer camber link ball stud in the outside hole and added 1 more washer under the inner ball stud and that helped a great deal with the loose rear end. Tires are not the greatest for traction, my son's Slash with stock tires had way more traction and control. I just have a light coating of the black grease in the diff and it seemed perfect. WOW what a blast!!!!!! I am not sure what class they will make me run in as I am getting a 13.5 this week I hope to run with the Slash's. I would like to try different tires, where can I get the stock wheel to mount them on.
