Guess on 1/4 mile time
So I have a 99 z28, mods in sig. Last year I went to the track and ran high 13's at right around 103-106. I was spinning first gear on the 10 bolt with horrible 2.6 60'. I'm curious to know what people think I will run with some upgrades. Moser 9" with tru track, 4.10 gears, spohn adjustable tunnel mount torque arm, and Nitto NT05R, size 275/40/17. Street tires that were on it were 235/55/17. Just curiousity. Dying to go to the track, but will be a few months since still getting snow and my daughter will be born in about 3 weeks, so I know the wife won't let me go to the track right when it opens.

dude the mods i have in my sign are similar to yours but im an auto car and the best run i have gotten with that set up was a 12.1 @ 111 with a shitty 1.72 60' in 75 degree weather. i dont remember the da otherwise i would give you that too. there is no reason you shouldnt be low 12's with a good 60', good shifts and some nice weather. Your 2.6 60" is killing you man! every .1 off your 60' is "roughly" 1-2 tenths of your quarter mile time. So figure out the math going from a 2.6 to a 1.6 60' it will be a huge difference in times. I'd loss those nitto's and get a really tire behind that car it will need it when you are 4,000rpm and up launching.
