Full team pack done(without helmets, steering wheel) with seperate cars so you can choose between the two depending on your taste. Changed the team logo in the menu and it will be changed too in the scoreboard too if you install the modified language file too.
For helmets I recommend ML's brilliant work which you can find here:
Will replace Mercedes. Don't forget to backup all your files before installing.
Included a modified language file for those who would like to see the team's name changed too but note that if you install it you won't be able to play online.
