Is this a single or dual mass flywheel?

[Deluxe 247]

I bought my e30 4 years ago and its time for a new clutch, it was used as a track car and when I asked the previous owner if it had a single mass or dual mass flywheel he said he wasn't sure but he had this picture. If anyone could help me id this so I know what to order for my new clutch that'd be much appreciated.

Looks like a single mass to me.

blueness.


The friction plate looks non- stock, from what's visible.
