They (WEC) have BOP and fixed development to prevent a spending war which should equalise the cars (or manipulate who wins) so each of the teams should get a fair crack of the whip and their moment to shine. I’m sure they are very conscious that they will need all the teams to ‘succeed’ at some point to keep them all.
I’m a fan of endurance racing so I’m keen to see how this all pans out over the next few years.
