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.

if those tires can hold and can get atleast 1.6 60' and you know how to lauch a 6 speed car with good air you should be low 12's as long as all the factors come together. On a terrible day you should run high 12's

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.
