I think it would be good for the sim to have the possibilitie to add "updates" for the bikes, like rfactor, for example, i have a wsbk bike with an akrapovic exhaust, and in the british championship the same bike uses another brand of exhaust, so i post this idea for lots of parts for example, rims, exhaust, wings, windshields, etc. and we don´t need to copy the folder of a complete bike and rename it only for changing a little piece, what you all think?
