The point is, it's extremely easy to get into indurance racing. You either build cheap car based on one of four spec chassis with spec hybrid, or if you really want to win, you have good engineers and facilities, you spend more money and build LMH.. But it's easy and it's cheap, just look how many privateers start in WEC and IMSA. There are even privateers that build their own cars.

And Rally1 isn't that far from LMDh. There are spec safety cell and spec hybrid unit. Space frame is easy to make and it's also cheap. Then there are the expensive and useless engines, which are all pretty same, and it's imo major gatekeeper for teams that would like to get into WRC.

So why not allow build Rally1 car in similar way to LMDh? Choose 4 companies that would build spec chassis and allow competitors to buy them. Choose 4 part makers for every parts that will be spec. Make engines based on road cars again and let everyone to convert the engine. Or force manus to sell these engines like it's in F1. And then just let anyone build Rally1 like a lego.

Well I wouldn't be mad at all if Rally1 would become semi spec series. After all now it's not that far from spec series with how much strict ruleset is there.
