I got this achievement during my WRC 2 season, Spain was the final rally of the season and you must reach the podium (1st, 2nd, 3rd)
But if you finish 1st it helps towards your Accomplishments
My settings are on Easy and no damage (getting used to the road layouts etc before I go full SIM mode)
But your settings shouldn't make a difference as long as you come on the Podiun
