Question to Pit stops (Moc or Set)

[Matthias83]

Hello,
maybe this time someone can also help.
Short question to this Scenario:

On this wonderful Racing track there are some nice Pit Stops on the right side.
Are they Mocs or exists some regular sets were they are included?

Cause the Award ceremony in the north is from the Set 8672 I belive.
So maybe the Pit Stops are also from Set.

Any help is welcome!

I think a combination of sets and MODs I think. I at least recognize 8375:
