First time I was out this year testing CAI'S the DA was good...400-700, ran in the 12.4's in 5 of 7 runs.
Next time out DA was about the same with bad traction and ran all 5 runs in the 12.4's, but that was with downpipes.
I've added coilovers since then, hoping to sneak into some lower bracket now if the DA is right.
I've had thoughts of traveling to one of those places that throw up negative DA on the regular.
Thx too!
