The rear carrier fits perfectly on my Golf estate, so it should also fit on the Subaru (and can be fitted without a towbar).

Hello,
Unfortunately I can't answer your question, as I sent the product back.
It did not meet my needs.

Yes, it works without a towbar. I bought it for that reason. But now I've changed the car.

And yes it goes on the Subaru 👍🏻

Yes, and yes, you don't need a towbar.
