Just got back from the track, my best was a 12.9@105.77mph with 2.01 60ft, so there's room for improvement on the 60's. Tires where at 12 and the most I lowered the pressure was 10.5psi.
YouTube - Sentra B11 SR20VE 12s Pass
Also got 2 pases of 13.0@105, 2 more of 13.2 @105 and one of 13.3
I'm very happy with the results, and I think Im the first all motor nissan here in PR running 12s
