"posi" is a term that chevy or ford (all the same to me) made up for their term of a locking differential.
You need an LSD (limited slip differential) if you dont have one. One way to tell if you dont have one is to jack the back of the car up, spin one wheel with your hand and if the other wheel spins the opposite direction, you don't have and LSD. Otherwise, good luck getting the back end to KEEP sliding...
So really, no not really any easy way to do donuts.
Limitied slip differentials transfer power from the spinning wheel to the oposite wheel. That's a super simple explanation, you can read up more online there's tons of stuff about LSDs (limited slip differentials)
And I believe positraction was a Pontiac thing

It's more difficult to do them with a non-LSD diff. However, it is still possible. You'll have to warm up both tires a lot so that they both loose traction very easily. After a few min of doing donuts, you're going to wish you never had. There are about 10 different things you should check after you've done one. And none of them are cheap to fix.
Front CA bushings, balljoints, rear shock mounts, rear shocks, rear sway bar endlinks, rear trailing arm bushings, rear control arm bushing, etc.
Take everyone's advice, it's not worth it.
