Beatrush diff support mount
 

Couldn't find a review. What do you guys think?

I think it's overkill. The poly inserts (currently from whiteline) seem more than adequate.

this just adds weight (in my opinion)

I'd rather have an extra 3-4lbs and a rock solid rear end instead of flex and hop, potentially causing broken diff.

Anyone else have it?

Just looking at that brace (and I am not certain about this) I get the impression that it locks the diff in place. That is, there is no movement. I don't think this is a good idea. Stiffer bushes yes, rigid no.

How does diff casing movement cause a broken diff?

Cusco also has one very similar to this. They all do the same thing pretty much.

i have the cusco on my car for a few weeks now. its a bit noisy and chatters a bit.. makes the whine in reverse too.. its weird but solid. idk if i want it anymore. kinda jus wanted inserts but they didnt make them till now

Anyone else have experience?

Wheel hop can turn into odd deflection and snap parts. The reason for traction bars and solid rear ends on drag cars.

This diff isn't designed to be solidly mounted. Add to that the fact that this bar doesn't use the forward mounting points and I'd be very worried that the rear mounting points will break. That's an assumption, but that alone is enough for me to not buy it.

You are correct though, too much movement isn't good either. That's why I went with the inserts.

I'm going to get the bushings but also looking at a cradle to build.
