I was thinking it be good if yu can have the option to have 1 sponser for the whole car like yu do in F1. Either as an option like 'Whole Car' or being able to have the same sponsor on more than one thing. For Example - having H2O2 for the front and rear wing and iRacing fohe engine and side pods.
As prsonally i tink it would be more realistic and teams can match their livery to the sponsor the picked.
