Just unlocked Endurance Legends, and just to conclude, one needs 36, not 37 trophies as shown on Endurance Legends screen (Why show it like that then?). So, PR 115 is enough, with an upgrade tree of 1321232 for 1,402,900 R$ and 116 Gold the cheapest, although by just 4 Gold. Now, just need to farm 90 Gold for the 919 Hybrid and that's it.

Thanks for this page, SlatBH , although somewhat imperfect at places, it definitely helped to have the data together, or at least to be able to compare it quickly.
