If you have a GST, these seem to be conflicting goals. That load transfer to the rears is gonna make the launches required for those sorts of times a little difficult for a FWD car without drag tires. On the plus side, you can easily swap out to some drag tires at the track.
I'm gonna soap box a little here because I used to have a crappy VW Jetta and lofty goals (didn't work out so well), so I can speak from experience here. With a goal like that, make sure you have the closest thing to the right tool for the job right out of the box.
That being said, it's your car, it's your project, do whatever blows your hair back, sir.
Hands down need some qtp's at the least for that goal. Check out richard33's car. I personally love my Quaife LSD in my gst. For corners and striaghts. So much easier to burnout and launch. I was launching at 5250rpm and with 10psi boost and cutting low 1.7 60'. No way your doing that on drag radials and open diff. My gst will be back at it once my hands heal from my surgery. I have everything I need to hit 10's

The quaife is significantly more durable than the factory FWD front diff that likes to throw the cross-pin through your bellhousing. And yes, it will help overall with traction better than the factory open front diff.
Some drag radials also aren't too friendly with our drivetrain, I would recommend a softer sidewall tire, as it will have more give.
QTP's are Hoosier Quick Time Pro (QTP) DOT slicks. They can be street driven, though I wouldn't recommend it on a FWD; and they have decent wear life in comparison to other options like MT ET Street's which wear away extremely fast.
As for tire options, it will mainly depend on what size wheel you are using to determine the proper choices.
Vids are in my profile. I havnt used a kaaz unit yet so not sure how it compairs. I've used more boost on the launch, but found for my setup around 10psi worked great for a good consistent 60'. I also do burnouts in 2nd gear to get more wheel speed, and get a hotter burnout. I use Hoosier qtp's for the front at track they are 26"x9.5"x16". And on the street run 225/45/17 hankook ventus v12's.
Nice! I'm still stuck in between quiafe or kaaz. Gotta do more research and see what I like more.I've run a quaiffe since 2003 and it works great , at the track with my qtp's it launches hard with no spin 12.6@111 1.9 60'
If you're intent on drag racing a street car, I'd definitely go with the quiafe; no maintenance required, allows a difference in wheel speed for the street, and more freedom on gear oil selection.
