I have cut numerous 1.7's and no slower than a mid 1.8 in my last dozen or so passes on my 235/60 BFG DR's at 16psi (100% stock suspension...no airbags).
My process is simple...
1. Roll through the water box (you have to at Atco)
2. Stomp the brake and start 'em spinning
3. When I see smoke in my driver's side mirror, I let off the brake and feather the throttle until I feel them biting.
4. Roll to the line...stage at 5psi
That's it. It's been my experience that they hook best with a nice burnout. I have about 3-4k on these tires. They're getting pretty bald, but I should make it through until July/August with them and another 1-2k.
