Upgrades for Australia. Front wing flaps are changing and they have had to make new endplates to accommodate this due to the new front rule requirements affecting modularity.
Should probably get more front downforce after this change
Will look for any photos of the new front wing today. I have this photo from Australia from Autosport but I compared it to a very similar photo posted from pre-season testing and it doesn't seem like anything has changed at all, so I think that's still the old spec out for Thursday.
