Going 9", what posi?

I'll be swapping out my 12 bolt for a 9" soon, but I need to figure out what posi to use. My raceweight is going to be around 3900 lbs., car makes 750 at the wheels right now. I may put the bottle back to it too, or get a larger blower. No trans brake, but its always on sticky tires. Its 99% street car, I don't get to the track much.

I'd opt for a lokar. The posi is the weak point in the rear. It's pretty much the best of both worlds.

I'd go spool, my buddy hates the locker on the street...... whatever you do do NOT get one of those trutrack things, those are total junk.

I'm assuming its an automatic being that you mentioned a transbrake. I would put a locker, and NOT a spool if you do street driving. You don't want to use a locker with a straight shift car, because it can lock, and un-lock the diff between shifts. Spools suck on the street.
