Do you mean client now? If, then you can set filters. Unfortunately, this setting cannot be saved, but the filters must be reset each time the game starts.
But I think you meant the server side, that is, a player coming on too big a ping couldn’t join. I do not know the answer to that, but I am following this debate with interest. This would be an idea almost worth proposing. Have you suggested this on the Wreckfest Discord channel?
