Cool! I will definately ask Mike for help if I see him. I am a bit shy at big races though! I do not want to bug anyone that is busy, like you said! He actually was in the room next to me last year, and I did talk to him a bit! However I didn't race 1/12th last year. hehe
Ok I will have to look at the car for that spacer thing. I don't think I have to shave the spacers, I think he means add more spacers the amount that you shaved from pivot balls.
I will see how it goes though. I might first try rounding the edges of my front tires more, see if that fixes the "grab" problem I am having causing the traction roll. Roll center is a good idea though I have been doing that on my pro4...
These tips are awesome... Anything else people suggest?
