Has anyone got that achievement? If so, then with which car and what setup (not asking about the track - Monza's the obvious place to do that )? I thought doing it in the 458 would be easy - after all, the car is supposed to do 340 km/h. Unfortunately, it (or at least the game's representation of it) seems to need a bit more room, than Monza's main straight. The fastest I managed to go before reaching the curva grande was 280-something km/h. The problem might be in not carrying enough speed through the parabolica, but I seriously can't imagine taking that corner faster without understeering into the gravel... I tried the Lotus as well and with some gear ratio changes I did 295 km/h, so I'm still just a couple of km/h short. Again, the problem might be in the parabolica, but this car understeers over there even more than the 458. Any tips?
