Shift 2 Unleashed DLC still available?

Hello

I know ... it is a 10 years old game (since release), but I am always interested in such games with old cars and tracks, like there was the Legends Pack for Shift 2 Unleashed available once.

As I recently bought the game and downloaded it with Origin, does someone know if the DLCs are still available and if so, can someone point me to the download location or give me a rough summary on how to get / activate them in Origin?

Thanks in advance.
