Central bearings weakness ?

[Facelvega]

Hi there,

I faced some troubles with the 2 central bearings with my B-MAX. I broke them very soon.
I switched from the steel factory bearings to ceramic bearings and I add the cool Aluminum Main Gear Cover from Yokomo.

I do not feel confident with the new bearings as my partner who is using the same car with the same set up broke his ceramic bearings again.

Did you face the same problem and how did you solve it ?

Thanks for your help.
