Sqonzalez,

Replacing gives you the option to go with an aftermarket 2 way diff, expensive but if you're serious about going to track with your car, worth the money.

If you want to keep the stock unit you're probably best off rebuilding the stock diff. Its not to hard to do and a rebuild kit, provided the diff isn't completely f'ed, isn't expensive (150$ ish).

The problem in both cases is installing the diff, you'll need to properly setup the ring and pinion gear and thats a job not everyone can do, certainly not something you want to do if you've never done it before.
