None of these are possible only the helmet because CM made the textures this year far more compliment than last year. The whole texture is mirrored .
To describe it better:
On the Ferrari texture there is the Santander logo on the rear wing left side, now there are only 1 of that not 2 unlike in the last year texture and there are no models to work with currently so it's quite hard.Other than default HD or DHD skins you won't really see custom skins like that.
I see. But is it possible to use another helmet and another drivers name in the Classic Grand Prix mode? So let's say, Jan Lammers helmet, screenname/standinglist with his name, and his name on the car?
