I know, FOAs are frowned upon, but I just wanted to know why, they seem like a good deal.
So here is my little straight out of the box tune up session I did on a pair that I am planing to run on a truck.

The seal head and piston, look at the burrs and chatter:

The bearings are also quite loose, I went ahead and made some bumpers for mine until I upgrade them.
