anyone wanna guess what my 1/8 mile will be

With the coils/ladders, and since you have a Panhard bar or Watts link to keep the housing centered, my first thought would be to look there. Problem I see with that is, it doesn't act up with the street tires? If you could post some pics of the setup, maybe we could see a possible flaw. Not trying to be a bad guy, but at your power level and the suspension you have (ladders & coilovers), you should not have these issues. Meaning hook and being extremely loose.

I should add that 805 has a good point on the bias/radial deal...........My opinion is, that's a issue on uneven surfaces and in the rain. On a smooth track, it should be almost undetectable.
