I have snapped several of these swaybar brackets on my 2.3-16.
I had much heavier brackets using spring steel made for my Cosworth and then in addition to the bracket breaking, the frame supporting it also cracked. So, I'd have been better off just having the regular strength bracket snap. On the other hand it wasn't much work to repair the frame.
It's interesting that on two consecutive days, I snapped the same bracket in the same spot in the same turn at Summit Point Raceway. When they broke they sounded like a shotgun blasts.
