Endurance Kings opens up with completion of Road To Le Mans. You aren't there yet.

You might Squeak by with a fully upgraded Porsche 918 Spyder concept and unlock Spirit Of Ferrari]}, but more likely, you will need the [[Koenigsegg Agera.

With Spirit of Ferrari, you will probably need the Ferrari Enzo Ferrari or the Ferrari 599 GTO to unlock Zenith Series.

With Zenith Series, you need the Koenigsegg Agera R to unlock Road To Le Mans.

With RTLM, you can complete with R$ only upgrades if you are pretty assiduous about Bot Management and slowing. You should win the Porsche 919 Hybrid (2014), but then you need Gold upgrades to reach the ten-lapper.
