I saw the slots in the plate, but didn't see that he had a plug like that.
Based on this picture of the original G-Comp UCA mount, almost looks like he moved the mount up??
To me, that's counter intuitive. Moving the mount down would add more camber as the suspension compresses, but moving it up seems like it would reduce the camber gain. At least to start.
I did ask him about it on FB, but I am not going to hold my breath. Not so I can duplicate it, just curious what the intent was. Feels like he might hold this close to the chest in case he can market it to other people. Which is fine, no hard feelings if he doesn't answer.
