You can get to the 10 lapper with just the Porsche 919 and 911, you will need to upgrade the 919 to PR94, to get passed 16.2 and 17.1 etc, which are PR 94, the 10 lapper is actually only PR 86. If you can afford the Toyota and Audi you can upgrade the 919 to PR93.1 (only R$ upgrades). If you can't afford them, you need to skip their showcase races so need to do the PR 94 events, I think 3 or 4 GC upgrades - see Porsche 919 Hybrid upgrades with PR, I think you'll need the remaining level 2 GC upgrade and three level 3, about 152 GC. Double check the PR values before you buy them: "These numbers represented are not fully accurate and may differ from the value you see in-game" this is because they change depending on the order you buy the upgrades.
