So I'm going back to the track this friday, provided we still have good weather anyways. I have an 05 v6 and I'm not really sure what the best way to launch would be with the open diff. My best time so far was a 15.1x at 94 with a 2.3 60'. I was on bald 235/50/17 falkens. I now have 275/40/17 nt555s, and no rear seat.
