I do not want to start a new thread, so i think its appropriated to post here.
Im just looking to install some spacers but here in switzerland its not easy as i thought.

We need a Gutachten paper, this is an certification that at the moment only one company has this certification, H&R or eibach or other else doesnt have.

The problem is that they want only for the bolts 300usd and i think its very very overpriced.

I was looking for some bolts and i think for the BMW x5 and X7 and newer models they only approved the Bolts with movable cone seat. Is this true?

Can i use normal bolts or do i need this movable cone seat bolts?

dimentions im looking for are m14x1.25x40 and m14x1.25x43
No, you can use the F15 X5 bolts.
BMW still use the fixed cone on their locking lug bolts. So the washer cone is not necessary.
In fact, my dealer service tech is working with BMW to replace all my 2 piece stock bolts with 1 piece cone bolts. One of my stock 2 piece bolts got jammed in the wheel and could not be removed without extensive "encouragement". My dealer service (a phenomenal group) are not happy with the 2 piece bolts. Reminds me that I need to get a status update on that action ...
Thanks for your feedback

Glad that you wrote your experience here.
I'm not a fan of this bolts either
