I'm looking for a recommendation for a limited slip diff for the Saab f40 6 speed transmission. They seem pretty pricey so I don't want to get it wrong.
Thanks everyone,
Daryl M

I got a Quaife off a vendor on Ebay. Cost about $1200 I think. Don't know if there is any other brand out there.

Quaife is the only option AFAIK.

Thanks guys. I didn't know if there were other options and at that price, I will be paying 3 times the cost of the transmission I bought, so I didn't want to get it wrong. The change out seems pretty straight forward. I found a video showing it being installed, but again, I appreciat the experience of you guys on the list, so any tips or cautions on the lsd install?

Quaife here as well.

I've always liked limited slip differentials but never had a traction problem with any Fiero that I have ever owned. The question I have is when is the traction problem evident and under what conditions?

I agree, my wheel spin problems have either been deliberate or the result of too much throttle in a low speed sharp turn. I believe the LSD is more of a FWD problem solver. Even under the most spirited straight line acceleration efforts, as long as the clutch wasn't dumped I didn't have wheel spin. I do have 245s on the rear so wider quality tires could be considered as a viable alternative.

and I might add that forum member Scott / Darkhorizon with his 9 second 1/4 mile turbo Fiero doesn't run one ether .
