Same here. The stock set up was fine but I had to wait on it to turn in and out.
I think I might be able to help you out. We have been pretty dusty this year. My guess is your probably pushing in and out of the turns? I am having great luck with AKA Ibeams (Med.), but if that is not enough run the high roll center in the front with no sway bar. That will help.... The 40g front ballast will add to that with battery forward. 2.5 rear sway will help to but I had to raise the rear roll center when I did that. I am running the rear hubs forward. I run 28mm ride height but try 27mm in the front and 29mm in the rear. Be sure the suspension is free.
I try a lot of things but this is a pretty good set up at our track, packed dusty, and pretty smooth.
