Any requests for a helmet design we don't have yet go here - Modding Requests
All our F1 2012 downloads (including helmets) have their own thread in the mod forum
If you download a helmet and need help with it, then you can ask in the thread associated with that download. The download will have a 'Version' Tab and a 'Discussion' tab. The 'discussion' tab will take you to the forum thread for that download
