Glancing Blow Achievement
With Damage on Full make contact with the wall at Monaco and win the Race
Set up a Grand Prix at Monaco and use any settings you are comfortable with. I would advise you to set rules and flags to reduced, though, as it could help you keeping ahead of the competition by cutting some corners and only getting warnings for it.You will not have to crash out in order to unlock this Achievement. Just touch the wall and drive along it slowly (make sure you slow down before you do, otherwise you WILL crash out) and go on to win the race.
