Default Need help launching my car!

I have a 98Z28 M6. I havent been to the track in awhile due to being deployed to Iraq. The last time I was there though I had a hell of a time trying to launche this thing. It was stock with subframe connectors and free mods. I was on a bridgestone potenza RE730 tire. I found that there was only a 50 rpm differance between spinning to the 60 ft mark and jumping and then bogging down at the line. I was trying the launch at about 1700-2000 rpm. Here is what my question really pertains to. Now after being deployed I have had the chance to do some other mods and wonder what would be the best method to the launch now?

Here is a list of my mods now:

lid w k/n
gms maf
ls6 intake
NX 100 wet shot (set on a msd window switch)
cutout
loudmouth cat back
subframe connectors
lca's with relocation brackets
pro 5.0 w lss
3.90:1 gear(stock axles and housing)
Nittos

Also wonder about the burnout since I have the nittos and used to have the street tires?

Also keep in mind that this is a daily driver and I am worried about breaking until I can do the clutch and the 12 bolt.
