Default what diffirent could i expect with lower diff?

i want to install a 4.10 diff before the summer, got a loudmouth catback and ls7 clutch/ls2 flywheel,

went 13.7@102mph in my first time at the track ever with the car BONEstock with 60f over 2.5s,

i dont expect the loudmouth and ls2 flywheel to do any changes,

but how much diffirent should i expect if i put the 4.10 diff?

I depends on your driving skill. 4.10's clutch and drag radials + good driver = mid 12's.
With a 60f over 2.5 you might do better with out the ability to spin the tires faster! I think there is more inprovement in your launch than gears. Gears make the launch even needing more skill.
Sorry for this opinion.

Does a drag race take you from one side of the island to the other?

LOL no the land isn't that little, whe are just so few that live here,

i know how bad the 60f time is, my clutch was toasted, and the car hardly drivable, but i had just got the car and this was the last open nigth at our track, so i just went there, literaly fried my flywheel and what was left of the clutch,

was on the oem 245/50R16 tires and had no grip at all, couldnt lounch over 1800-2000rpm,

now i got better tires and new clutch

In my car, I dropped from a 13.47 to a 13.00 just by changing from 3.42's to 4.10's. I would have dropped more if my rearend could have handled the power.

Given stock (GSC or GSA??) street tires launching in the ambient temps you have there (more likely than not, a phenomenal DA, giving you even more power, even on an otherwise stock car), I'm suprised you even got a 2.5 sec. 60'!!! Get yourself some M/T, Hoosier, or Goodyear drag radials, and heat them up with a 10sec. burnout, and try again. Which clutch did you install? What tires are you on now?

Did Zs come with Eagle F1 runflats also or was that just SSs and WS.6s? The condition of the tires also comes into play aswell.

Yeah ive been saving up for a 12-bolt for a couple months. Im hoping to get it in by the end of the season, so i can see what this thing will do. I know better to take it to the track now, it will snap like a twig.

Dude,........Last summer I remember see'n some kid in the burnout box,......He granaded his in the box. No...AAA or nothing and he lived 130 miles away. He was cry'n for a moment and his father walked up to him and said "Maybe we should have changed the oil back there last month huh?!".... I couldn't help but laugh my *** off not 5 feet from them when I heard that!

Imagine how much that **** cost to tow 130 miles!!!.... I'd **** a brick if I ever saw that bill!
