Now that there are spec rival events and updated AI, it seems entirely possible to have single player spec series that’s rotating just like the open series builder’s cup (E, D, C, B, A, S, R). Could be like GT4, GT3, P3, P2, P1, Hypercar or something like that, or rotating between all the spec options.
There is just no way in single player right now to have spec series racing – it’s not even possible in free play. Would really love some more spec racing content with all the race cars in single player please!!
