lvl 4 parts

[2fast4all]

Does anyone know how to unlock lvl 4 parts for all or most cars, Ive beaten the game a long time ago and only unlock lvl 4 nos for a some ride, and suspension for my supra or something. Do you have to re-race the raceday to unlock them?

Thanks

Non-cheat. Try the harder, boss racedays... but yep, they're prizes only without resorting to "unlockallthings"
