My car was very similar to what you are experiencing. I ended up where you are with the front tires for 19t, paired up blacks. But I had to go to a pair of pinks in the back. I also ended up with a purple RF spring and I know I am running more LR than that, I can't remember how much though. I also had to move the LR out farther than Danny B recommends. Actually I race with him weekly and he is the one that was tuning the car for me the first time out with it!! He wasn't racing that day and he would just sit at my table and tune things for me, it was nice!! I would maybe try centering up the pod? Also more LR weight, mine is over the 11.5 that Danny recommends I believe, not much but I think it is higher. Also throw some stiffer front springs at it. I don't know where the silver spring is compared to the red associated we run so I don't know where to go there. Also is the back end stuck too much or the front, it seems as though your front may be stuck too much, the car is steering too much, and maybe the rear isn't stuck enough to drive the car off the corner?? If that is the case maybe that black RR needs to be changed. I know guys around here run paired up whites in the rear but some also run paired up blacks back there too. This stuff may help but it may be way out in right field too!! Try some of it and see what happens, maybe Danny will come on here and tell me what I said is wrong or maybe most is ok. Later.
