A couple of optimizations I would suggest - Firstly, change the name of the folder in the download from "corvette_c6" to "urd_egt_corvette" - it will make dragging-and-dropping the skins into CM much easier.
Secondly, and more pressing; instead of having multiple redundant KN5 files in each skin, have a single set of KN5 files in a separate "Extension" folder in the car's primary directory. That will help greatly reduce the install size of this skin pack.
