This is a re-upload of my Michael Schumacher 2004 helmet but I have included the driver suit too 
In order to see the suit in game you need to use Ego ERP Archiver to replace the 2004-ferrari_livery_d.tga file in F1 2017/asset_groups/animation_package/scenes/incardriver/1980/incardriver.erp
If you want to see the gloves you need to replace the file career_ferrari_helmet_d.tga in F1 2017/asset_groups/animation_package/scenes/incardriver/1980/incardriver.erp and your helmet file that you decided to use for example: com_06_helmet_d.tga
The tricky part is finding the correct career_ferrai_helmet_d.tga file to replace because there are four of them you need to replace the third one from the top. I hope this makes sense
And please as is the usual PLEASE BACKUP ALL YOUR FILES!!!
