Sorry I took so long, I meant to PM you and don't know how I wound up here. I'm pretty new to but I had the same crazy traction roll problem and adding a washer or two under the front of the rear pivot block adds anti squat. It will give you more on power steering but because the rear doesn't squat as much, it actually slightly reduces rear traction. Therefore it helps to reduce our traction roll problem. It's not a fix all, but definitely worth it, I took it out once because I went to a new track and I couldn't drive the damn thing so its always in there. Don't worry about asking me questions, I'm relatively new as well, and know what jerk offs some of these guys can be!!

Hey Jeremy, have you tried adding a little anti squat?
