My car has an open diff with TC.

This setup annoys me and I am thinking that with the planned addition of a supercharger, 300 off kw's will require a limited slip centre.

Whats the best way to go about this, and would I be better off getting a diff shop to build me a centre, or get a wrecked diff from an XR or similar?

Regardless of the supercharger addition I want an LSD.

They are much more fun!

Thanks for any input......
