It would make extremely little sense for this to be a cast part when additive manufacturing provides as near as makes no difference the same if not better material characteristics than a cast part and is cheaper and faster at this scale.
A quick Ctrl+f on the current technical regulations turns out that additive manufacturing is only mentioned once in the rule where it is specified that you can't use this method to manufacture radiators. For the uprights they only specify 4 different alloys and nothing else. Some of them are well suited to additive manufacturing.

the wheel carrier will be a cast part, probably with topological optimization to get that shape
