Rear sway bar mount breakage WRX

[NitroTrike]

Has anyone had the passenger side rear sway bar mount break off of the frame?
The scary part is, when it breaks, the sharp steel rubs on the gas filler
neck!!! The car has whiteline bars front and rear. My only thought is the
mounts cant handle the stiffer bars??? any thoughts?

How stiff of a bar were you running? It's not that the mount isn't strong,
it's that the mount is strong enough for the stock swaybar (and more so).
Not the first time it has happened, but if you wish to reduce roll and
stiffen your suspension, you might want to think about doing with
a new set of struts/springs, not by running very high bar rates.

I thought you had to put stronger mounts on with the stonger bars.

I looked for aftermarket mounts. Its not the one that holds the bar on, its the
mount that goes to the frame. I ordered one from the dealer...a whole 12 bucks.
It must be made out of REAL GOOD STEEL, huh. I still think my "steel washers
welded on" reinforced one will hold for a while

About halfway down this page there's a recommendation to upgrade the mounts
with a bar larger than 22mm
