Thanks for the feedback Mike.
I went to the 2degree casters to get a little better turn-in. I also want to try a sway but the hobby shop hasn't gotten them in yet.
BTW, the car is working very well (always top 2 or 3) just looking for that little extra.
Anything else to try? What about low roll center? I have the blocks, just haven't wanted to do the bumper modification yet.
