Its not as much "grinding the wall " its more like riding the wall to save the time of braking and losing all that speed.
"grinding the wall "
That's not news. You know the easier method? Switch your controls so R is accelerate. Than put a rubber band over your psp so it hold R button.
That's what im doing now, 2 laps round test course with a Veryon and N1 tires will get you 2.2mil in an hour.
And no it's not cheating, it's just getting round things and being clever.
So wait, you say that with Pescarolo I will not have this problem?
^ That's why you don't choose the Veyron when in rubber-band mode. Get the Pescarolo C60, set Same Manufacturer option to off and you'll always be up against 3 Escudos, irrespective of your tire choice. Your minimum cornering speed due to grinding will still be higher than the Escudo's top speed on the straights (but they'll still catch up because of stupid RBE, they won't pass you though).
I guarantee you will NEVER spin out. Even with N1 tires and all aids off, on Pro physics.
Try the grass on the final corner. Due to some unexplained reasons you gain 5mph faster from it, AND you are taking the inside line.
Oh man! i thought i was going to be the only person to know about that!! haha
