I'm not entirely sure about the upgrades, but if you slow the bot's enough, and manage them, you might be able to complete with only first level, although the 'complete within the time limit' challenges might be problematic. As for CRB though, that stands for Clean Race Bonus, which as you probably know is a reward that is reduced by the amount that you drive off track and collide.
