I'm seeing a ton of options without bushings. Bansai, Odula, HPI 2-in-1 and all the clones of it. With bushings, you have the Sikky for ~$550 and that seems to be it.

I also have the AutoEXE front and rear under-bracing, trying to keep that if possible. Definitely won't fit with the Sikky brace, also not trying to spend that much on a brace..

 

I have used a few of the braces, all good options but i am currently not running any. I am using the nylon mounts from rx7.com by themselves and they work very well. I do some launches but i dont drag race. I use them with the banzai transmission brace and i have found that the combination of them 2 is awesome especially if its a daily driven car. A lot less vibrations transferred in the cabin.
it is more labor intensive to do the mounts as opposed to a brace but i do prefer that over any brace. It will also be much cheaper to have it shipped to thailand. Or even cheaper to get them made locally probably.
food for thought anyway. Others wiser than me may disagree but that’s my experience

 

Did you remove the diff braces because of vibration concerns? What diff are you using?

 

Partially yes but i did try it on several of my current and previous cars.
i have used the carbonetics diff and os giken 1.5 way diff.
