Cool truck!!!!

I don't have to much to contribute about down force and aerodynamics, I will leave that to our local experts. With that said I think your going to have issues no matter how much down force you have have on a no-prep track with the power your making. On my my car running around on the street running with my QTP Hoosier's it will spin the tires and move around on me and my car is only a mid 9 second street car. I have two friends that have the fastest AWD Talons in the world both in the 7's at 180+ and there is no way they can hook on a no-prep track.

I also think your 60' is what is hurting you the most. You should be at least around a 1.40 60'. Even on a AWD you have to hit the tires hard off the line and keep them planted.
