Honestly, some of the TKart stuff doesn’t seem to make sense to me. It might be the translation from Italian to English or the articles are written to simplify concepts.
It is interesting to note in the article that OTK claims that magnesium is a better conductor of heat, which is not the case (or at least that is what I understand).
Yes, one major reason for Aluminum in the wet is because it corrodes less than Mag. That alone should justify Al over Mag.
Think about where the tire heat is being generated and then think about where the heat paths are. I believe a more rational explanation might come through.
It seems that some of the information that comes out from the factory is BS or is not what the factory is saying or its’ being misinterpreted.
