Nowhere near as good as the aftermarket ones from what I have heard but never drove with one only the TRD mechanical one I have and it make a massive difference over stock in both handling and traction terms.
hmm ive got the opertunity for a lsd box but im not sure its going to cope with what im gonna throw at it having doubts thinking itl be a waste of money. might jus wait n save for a aftermarket lsd.
wait and save mate..
i ran a lsd box and wasnt much better with my power, eventually i wore the lsd out..
so waited and now bought a cusco lsd instead, difference is like night and day..
