It's true that our eclipses have an open differential, right? That means only one wheel peels out during a peelout?

Anyone know about upgrading the differential? Like, what companies make differentials... and what kind of differentials are available? (like, even when i play gran turismo i have no idea what means what)

I'm just trying to learn more about it, and to plan ahead for that one day when i actually have the funds to get it done.

thanks in advance.
