Yes, sorry for that, has been for the impact of seeing a so big file posted, I've downloaded it now. I'd already read that you plan to make carpacks about each car model with the various versions, as written in this page (all can't be carpacks, though). Well, in this way is much better and worth, but has to be used one .ar file, for textures and sounds sharing, otherwise if separated would be better release them in separated archives too.I wouldn't make it a huge carpack, the size would be too big. I just included the ones I did so you don't have to download many files to test them. They will be split into smaller carpacks of three to four max.
From the screenshots, what's to fix for all is the shadow, at least the sizes to better fit the cars.
