Moustagua
the gloves are simply the Grosjean's one with a little color change (gold to red). The gloves are in the incadriverxx.erp files, so i just export them, change the color in PS and then import them in all the erp files where the personal gloves are located. they are name unbrandedxx_glove_xx. You just a have to open each erp files from incardriver and frontend directories of the game with EEA 6.1 and check all the files to find the correct one. You just have to change all the correct files in all erp files for correctly have the new gloves in the game...

As explain above for the gloves, the suits are located in several erp file in incardiver and frontend directories.They are named unbrandedxx_livery. There are two files the livery_d and livery_s. you have to change the both in each erp file where the suit can be find. For information, all the suit i made for F1 2017 and 2018 are comatible with f1 2019. You can use them but not yet the caps, shoes and gloves. I will convert them as soon as possible. but for the suits themselves no problem...
