    Are you sure? I don`t know the rules for the current WRC 17 spec cars exactly but at least for the previous generations both titanium and magnesium was prohibited, would be strange to allow it now when the cars got enough more expensive anyway..
    But if they allow it again than sure why not

    I do not think Ti is allowed for the control arms, but is allowed for certain components such as springs etc. The rules still restrict certain components to be made of a specific alloy.

    Ti is not allowed unless it is basically a sub-component of a catalogue part. Suspension components are not part of that.

    Mg also not allowed other than the wheels.

    How would the FIA be able to tell what material is being used without some destructive testing? Seems like it would be easy to hide, particularly bits that are hard to get to, e.g. buried deep in the engine.

    They wouldn't, but they sometimes act on tips and that's when they know exactly what to go look for.

    In case of the engine, it is disassembled to the last bolt and nut and each and every part is inspected and characterised in the homologation. And it can be checked to this level of detail at any point if requested. Same for suspension or any other parts worth using exotic material on, all are physically handled and any obvious ones would stand out to experienced inspectors.

    But more to the point, if you think about it, it's the "obvious" major items where one can gain the most advantage by using fancy materials, so it's not hard to have in mind already the usual suspects. Saving fractions of grams by using Ti bolts in some hidden location, for example, is out of scope of WRC in my opinion (not yet anyway). If the rest of the car is so perfect that you're delving into such minute detail, then you should be winning the championship anyway.

    They can simply weigh it. A part that is said to be steel, but is made of titanium will have a different weight.

    I don`t think they use Mg wheels however as there`s a minimum weight on the wheels, 8,6 kg (if it`s still the same s it used to be).

    I don't know if anyone is using it, but it's allowed.

    I'm pretty sure many teams use magnesium rims. At least many R5 teams use them. They are not super light as anyway there is minimum weight, but they are much stronger than alu.
