Had it at the track a few days ago for some practice. I left the brass on and liked it as it was. I definitely have more forward traction. It was spooling the diff so that needs to be adjusted, I'd like to try the gear diff again to see what that does.I think that with the diff tightened i can tighten the slipper a bit and get better acceleration out of corners. I think I have everything where I want it I just have to switch the esc out for the Novak and mess with the geometry and shock package to make it perfect. Hopefully the next time I'm at the track I will be feeling better and drive better to see what its really doing.
