I answered on FB. 1, the car just looks loose in general, and some of it is driver induced. Let some rear bar out. 2, as someone who went from a TruTrac to T2R, the bias ratio makes a difference. I went the opposite direction you did (TT to T2R) and it pretty much eliminated my inside wheel spin out of the box and got even better with shock tuning.
