I know ideally we would but with the diff brace doesnt it stop the movement(for the most part) of the rubber bushing?

 

No, the brace is stiffer but I would not trust it as a "I'm gonna use this part so I don't have to change this other one" type deal. The stock bushing is too mushy and should be replaced, why do you not want to change it?

 

Just as a little help to visualize, look at Z1s video on it, it still moves a little with both the brace and their poly bushings.

 

Was more curious than anything. Ill do it all but figured it might not be as necessary when looking at how the brace holds it
