Well, the best i did with the nittos is 1.990 which, for me, isnt bad. I know i can get it down to a mid 1.8 or so. on the time that i did a great burn out, the guy in the right lane couldnt stage his damn car---took him, no lie, 15 seconds.... there went my heat. also, that was on like 20-22 psi in the tires.... nobody had a gauge.
