some people say that its not worth it in a v6. i have one and i love it. it all depends on what you do with the car really. $200 is a lot more than i'd pay for one from the junk yard though. i have an slp zexel torsen one that i bought from slp for $120 i think. and, that was basically new.
edit: i just realized that maybe you meant the whole rear end. $200 isn't too bad if its the whole rear end. like he said, find out what gears it has first.

Keeping the rearend from unloading on you in a corner is very important to me. And open diff will not allow you to handle as well as a posi on any car regardless of engine size.

I bought the slp posi for 99, plus shipping.
I have yet to install it, however my s10 had it in it, same engine. Yes, it needed it in that light rear-end.
I want mine more for handeling then power traction.

maybe mine was 99 plus shipping, i don't remember. anyways, i needed it in my car! before it, i had 3.23s with an open rear and could not hook up! then, i went to the posi with 4.10s! still couldn't hook up on the street. it was awesome. now i have that posi with 3.73s and newer tires and it doesn't spin quite as bad. however, it will still spin pretty good.

I have been told that if you tend to drive on the wilder side on the street, a posi will get you into trouble. You have to really tone down and think ahead of time. Or you can find your self out of control easy.

I need to swap a Posi untit into my 3.42 rear. I can't hook for crap, I could probably know half a second off if I had a posi. You guys are saying SLP sells a posi for 99 bux? What's the part number, I want one

i think that they sold out of them. they were the take-outs from new camaros and firebirds. check ebay though, you might catch a good deal on there.

Oh well im not getting it cause they won't lower the price and they won't let me just take the part out of the rearend. I just wanted one cause my car spins the right side rear tire all the time even if you just give it a tinny little amount of gas.

So they were going to sell you the whole axle for $200? That's not a bad price... but I guess it had really high gears in it compared to your 3.42 that you've got now?
Yes a posi is definately worth it... i miss mine.
