now come on, power upgrades on a le mans car against other le mans cars, thats just cheating. basically any b-spec driver should be able to win it no problem, in fact thats the race i've been using to level up my low level drivers. and they win with no power upgrades, completely stock, just full downforce and maybe play with the gear ratios if you have to. make sure you keep the drivers stress level up at maximum or he'll get owned. i found the low level drivers were pulling way faster lap times on that race because they just hurl themselves into the corners full tit which is fine on this one because the car is capable of it, where as the higher level ones slow down, which isn't necessary at all.
1. create new driver.
2. win indianapolis like the wind, go from level 0 to level 7 in one hit.
4. ???
5. profit
