Project CARS 2

Pretty simple achievement. Just head to Quick Play in the main menu and choose Custom Race. Disable the Practice and Qualifying in the Session Settings. Go to Race Settings and set Duration Type to Laps and Number of Laps to 1. Save it and choose Track Select and select the Imola track. Go to Vehicle Select, scroll to Ferrari and choose any Ferrari (I chose some of the faster Ferraris to make the race faster). If you wanna lower the difficulty before you start the race, select Opponent Settings and drop the opponent skill level to 0 and save. Now simply hit Start and head into the race. Complete the lap, go back to the event menu, choose a different Ferrari, and start the race again. Repeat 2 more times and the achievement will pop after you complete your 4th race with your 4th different Ferrari.
