It would be good, but only for Who has engine at level 30
Just thought some more about this idea. It can be setup so that if an engine supplier were to go into an engine point deficit due to using all of their surplus engine points, then points will start to be taken off the engine tuning stats, randomly to make up for any shortfalls. Thus making this not as good as you would think for level 30 teams.
Also, I would suggest that said engine supplier sponsors can sponsor up to 3 tokens and $1.5M worth to 1 car teams and up to 6 tokens and $3M for 2 car teams per race. This would eat engine points much faster and lead to the question of recinding said sponsorship commitments.
Finally, I thought that it would have remained unstated that you cannot sponsor your own team. You can only sponsor other teams in the game.
