any ideas?
We need someone to do some focused testing. I choose you!
Seriously, I have no idea why adding even shims top and bottom would change anything, unless it has to do with polar moment of inertia or arm twisting or shock tower flex or side loading the piston.... all of which seem like they'd be incredibly subtle.
Adding shims at only the top or the bottom, however, seems like it would be similar to making a very small shock angle change, when moving to a different hole on the tower would be too big of a change.
