Guys does anyone know how to change your upgrades while in the garage, I can select them or apply before a weekend in the main menu using the blackpain mod interface, I can change tyres car model etc, After starting a weekend I can only seem to select them in the garage and not apply them, is there some special button, also I put my F1 mod in a fresh vanilla gsc2013 but can't find the upgrades anywhere.. any help please.
