What Porsche wheels are these?

I think you'll find the Cayman wheels are very similar, however the hole in the spokes of the wheel are at the inner part of the wheel.
Where as the Boxster oem 987 wheels the hole in the spokes is on the end/outer edge of the spokes, and you'll find the Cayman spokes are a bit thinner than the Boxster spokes.
I know this as I have the two sets of wheels mentioned in this thread, will post photos when the net is up properly.
