Sponsors award bonus credits, liveries and car upgrades upon completion of their tasks.
Tasks include things like …
-complete so many laps in so many rounds
-finish above a certain position so many times
-get so many lockouts (place 1 and 2 in a round)
Always look for the sponsors’ objectives that you think you will be able to complete easily. Don’t go for ones that would be impossible (for example ‘place 2nd or better 3 times in Elite Cups’ will be very difficult).
To access the Sponsors page, look for the Sponsorship tab on your Team page or go to left menu… Team…Sponsorship.
Once the objective has been completed you can cancel it and look for another.
