Two weeks ago my best run was a 12.4 on streets but only with the traction "on". Tried it on a whim and it helped cause I had no traction at all. Last Friday night my best with Drag radials was my first run with a 12.5 then the times only got worse from there. I was expecting a lot more but air density and track prep can also kill you. Even with DR's I have no traction. Got to learn to lean into the throttle gently.
