During the Test Season and Pre-Season period, it was possible to change the affiliation contract with a manufacturer every new season. However, when the ‘FIA Gran Turismo Championship' 2018 Series starts on 20 June, the affiliation contract with a manufacturer will stay in place until the end of the 2018 season.
The affiliation contract with a manufacturer will play a large role in the upcoming Championship, so make sure to have a long-term strategy in place when selecting one.
Thank you for your understanding and please continue to enjoy Gran Turismo Sport!
