What's the cons of a LSD over an open differential?

[truwarrior]

I understand the benefits of a LSD over an open differential but what are some of the cons of having one over an open? Is a open differntial safer for high speed corners? more reliable? Cheaper to manufacture? Not sure why cars would come with a open differential when a LSD could be used instead.

Thanks!

Cheaper. Plain and simple.

After some further research I think a open differential would offer better tire wear.

What are you trying to accomplish with the car? Maybe better tire wear but would that really matter when put up against all benifits of an LSD?

I guess my main concern is if a LSD is just as safe or safer then a open differential. Say if your going around a high speed turn and instead of one wheel spinning with a open dif you could now be spinning two wheels leaving no traction.

No no no, that would only happen with a locked differential. An LSD is exactly what it's name is, a Limited Slip Differential. When cornering, a LSD will send power to the outside wheel to improve cornering. When going straight, it will lock up to provide maximum traction.

A downside to a LSD, at least for some makes, is chatter from them when they are engaging and disengaging.
