The contact point in your set up seems to be at the top edge of that aluminum disc too. If that pic is at full droop. I bet it would jump over the stopper at full compression. Are you using G body spindles?
I am using Blazer spindles so I was thinking it's the odd combination of non stock parts. UMI control arms, the tall ball joints and Blazer spindles.
I didn't want to sacrifice any steering angle. It's already crap at 25 deg. Are all G bodies like this?
So as UMI suggested, I drilled and tapped the spindles for a 3/8 socket head cap screw.
