I was thinking about this today. How about the default rFactor 2 helmet is mandatory for mods. Even if there are no upgrades at all, there would still be one which was default helmet or modders helmet. I am just thinking that a helmet should be able to carry over from car to car... same design. Same could be said for faces??
I think they should rewatch their driver model in general. It's TOO small. Personal helmet design opportunity should be great also.
