Hey I am acutally not a saab owner, I own a cobalt ss supercharged. Our cars share the f35 transmission, I was wondering which 9-3's have a limited slip differential? any help would be great.

 

I don't think any 9-3's have a factory LSD. Have you considered a qualife unit? You can't beat their warranty...

the option on our car was the quaife unit, I was hoping to not spend 1000 bucks plus labor on one of those.

 

well there is a cheap option, but the power output of the cobalt SS is pushing that option quite a bit. I know for a fact that OBX lsd's work quite well under 300hp. They're two times cheaper than a qualife, but for anything over 300hp I would not go that route.
