That looked great man! Good job on all the work. I don't understand everything you're saying but I do understand some of the words in your language are same as Spanish. Wish you are in USA, I want my wheels changed to 3 piece but I can't afford it. Lol... anyways, cheers 🍻
If the spokes are the ones to absorb the load of the wheel chanelling it to the center as a 1 piece wheel then, making it 3 piece makes the screws around the face, become the load absorbers. Just my opinion.
