Addict ics is shit, well ics in general is shit, so yeah either cut the top off the fork off and put in a starnut, or you can not cut them and put the starnut in from the bottom but it'll probably take a lot more time.
The metal of the SCS like stresses the forks because they're not normal Aluminium. Get a different fork or run ICS. I watched Matt's snap like a fucking pencil, he like hit it off of a ledge and it snapped.
