I also see they now have an F8x option. Anyone know what the diameter of that one is?

Calling VAC tomorrow to see if I can do an exchange.

What did you end up doing?

I had a 5mm h&r spacer on my 2016 550i xdrive and it had vibration so i ordered 3mm spacer to clear the caliper. I'm waiting for it to be delivered. They both are hub centric spacers the 3mm and 5mm, do you think the 3mm will cause a vibration still?

The website says: To avoid vibration, 3mm spacers work best with wheels that have a flush mounting surface. Wheels that have a bevel around the mounting surface will not be fully seated on the hub and a vibration may result.

I think the 343m has a bevel right?
