very very very bad drag radial best so far was 1.892 60' ending in a 12.2 @115.63. I use these bad drags becuase of the NA rear. THey will give more traction then street tires but less then good drag. Not to mention back in march i cut a 1.726 60' but missed 4th gear. I think that was a 12.0 run. Anyway, this is all coming from a heavy 2+2 conversion with a 240pound driver so keep that in mind as your think about the numbers.
