i just put in a Cusco RS 2way lsd and J's 4.44's. i was wondering what fluid would you recomend for the diff? i've been using mobil 1 then i tried redline shock proof. then the diff blew. but i was wondering if anyone had any advice with the cusco? thanks

 

What does Cusco recommend? - I have warned against use of Shockproof in the stock diff, but have no experience with Cusco.

 

i have no idea what cusco recomends. the whole book that came with it is all in japanes so i have no idea what it says.
