Bushings. You see the BMW symbol on the rubber, so it's genuine part. They do put date codes on this, which would also confirm if they have been replaced in the past.

I had issues with the other front suspension arms and ball joints, and decided (even knowing my torque bushings were only three years old) to do EVERYTHING all at once - so you have a "like new" reference. Since you have everything apart, why not?
