Well I vacuumed the track, and between that and 10% higher humidity today my ProStock went from a fast lap of 3.8 to a 4.3. So I switched to PN KSM Soft Radials( very worn), and went to a 4.1 with the steering d/r set at 90% down from 100%, last I removed the top disk of my DDS and I went to a 3.9 fast lap and much more predictable car with an avg lap of 4.2 over 40 laps. The weather is supposed to change here over the weekend, so we'll see how it effects the cars.

A bit later I tried running my Box Stock, which I had almost new KS-M Soft Radial rears on the R8, and it had WAY TOO much steering even with the D/R to 75% I was on my lid if I had any kind of speed through the 90s! So I swapped the almost slick KS-M soft rad. off my Pro Stock and the newish radials off the R8. I'll run them tomorrow, and hopefully they will balance everything out.
