Wikipedia has guidelines on how to use categories and when to avoid categories. Wikipedia also has a page listing pros and cons of lists vs categories vs navigation templates.

Then again, Wikipedia has several million pages while this wikia only has several hundred.

But some discipline would be needed to keep the category links to a minimum - for example, I don't think there is much point in having "Nissan" and "Nissan Silvia" both added to "Pure Stock Challenge" ("Nissan" is kind of redundant in that example in my opinion.)

In my opinion, the problem with the current method (adding circuits to series categories) is that is results in circuits being in a hundred different categories.

Go the Mazda Raceway Laguna Seca page and scroll down to what categories the page is in. The list of categories is longer than the page itself!

You might as well create a new article called "List of series containing Mazda Raceway Laguna Seca". Putting it in a list also allows you to show which variant is used and what event type it is.
