Hehe, I did this with mine a while ago. I ended up changing it back because it gave it a massive vibration. I used a different setup, though; this looks like he used PGM hubstack posts. I did a different method, which left the caps sticking out far less than this.
All in all, I’d say it’s not really worth it. I’d just pop the caps off and simply put on real hubstacks. otherwise, it prolly won’t work very well.
I know how too but not sure if I trust myself too. Have to actually cut the cap off perfectly and use the PGM Kit, then cut the cap so it resembles a z stack like bearing seat.
