You were launching at too high of RPMs on street tires. Your trap speed is good for 12s, but I'm sure your 60' suffered.

Out of curiosity, what RPMs are too high?

Well with that type of power he has, he would have to feather 1st and 2nd to get any type of traction. I wouldn't launch anymore then 2500 on street tires.

Well, just to be safe in case the OP missed them:

What mods do you have that can get you into the low 12's? Automatic or manual (two different rearend housings)?

Looking at boosted Z's, it's usually the axle that goes. If it was your axle(s), there are heavy duty options.

Sounds like severe wheel hop and then the axle popped. Until then, you'll be "launching" like one of us old guys, nice and easy.

Mind you, I've never taken this car to the track and don't intend to. There are much better platforms for that type of driving than these cars.
