I have a set on order now. ![](https://www.miataturbo.net/images/smilies/smile.gif)
Suspension is just TEIN Super Street, swaybar is a Whiteline solid bar. Preload should have been zero if not very close, I purposely lowered it onto some ramps to tighten.

It's the twisting of the bracket that causes it to shear. The aluminium blocks help absorb the weight/stress from the bottom of the bracket so that its not completely bourne by the bracket, reducing the stress on it.

I have seen this issue over and over and over again. Especially on the old C-Stock autocross Miata's. A big front bar plus R-comps usually ends in this type of failure. The problem most people have with the Racing Beat bar is that the bushing are too tight and the bar binds, basically making it untwist-able and the mounts then fail. One possible fix was to shave the flat bottom of the bushing down so that when the C mounts are tightened the bar can move freely. I chose to put a large washer between the C mount and the sway bar mount on the car. Not sure if that is clear or not. Basically, you know you have the bushing loose enough when the bar is not attached to the control arms and you push the sway bar up, and the bar slowly drops down.

I had this happen last summer at some point. I had NO idea, I only figured it out when I was swapping onto the winter storage wheels and both brackets were fubared. I was running the stock '97 bar too. However the car did have a thick bar (I think RB, but not sure) on it for several years before I bought it. I suspect that weakened things and the mounts just finally went when I was driving it.
Luckily it's not a hard thing to put the new mounts in though. Just annoying that you need to pull the rad.

FM/AWR mounts are in the car now but talk about a PITA.
The NB lower radiator brackets had to be modified to clear these mounts. In addition to this, the mounts were slightly too narrow so had to really be "persuaded" into place.
Did you guys have these issues?
