The time difference was about the same at the 1/4.
I tree'd him bad, that was about it, but a win is a win, and that was my best run so far.
Speaking of tires and suspension, I just have +1" 6 leaf Espo springs, stock pinion snubber, Monroe-matic blue shocks and 275/60/15 Coopers. I ran 19 psi and had a full tank of gas and an empty trunk.
