I would like those BMW shops to explain to me how a washer under pressure can break and come out of its housing, could it be that they break when the CH spun?
I think a stronger bolt can solve the problem just like on McLaren.

Personally i prefer hubs like gintani and precision dynamics which are a key style design.

2 pins are enough, the key is knowing how to make them so they are durable
