hi just posting question I have encountered during game play
1) Will the Difficultly level affect the performance upgrade you unlock?(I relized it deos to the unique upgrades,but how about just the normal ones which u buy?)
I suggest you to choose 'hard' in tournaments (specially drag) They are easy and you get (illogically) too much money, about 6250 if Im not wrong.
If you like easy things, choose easy in chronometer events and other difficult races.
