Anyone tell me what these are and where they go?

When I bought my E90 M3 I was given a couple of threaded pins by the previous owner. He said they were "pinion pins" and that he took them out to help handling when he autocrossed.

I would like to put the pins back in their rightful place, but a search on "pinion pins" didn't turn up anything useful to tell me where they go and how to put them back. I would really appreciate guidance from anyone that can point me in the right direction.

You'll probably find more with more googling - that's the first thing that came up searching "BMW 92 pinion pins".

Thanks! I searched BMW E90 pinion pins and came up with nothing useful.

err - typo, the search was E92, but anyway - glad an answer was easily at hand

They are front end alignment pins, used by the factory for initial alignment settings. They are in the top of the shock tower. He would have pulled the pins out so he could add more camber.
