Version 1.11 (27 November) can safely overwrite the previous version (version 1.1, 25 November).
These skin packs serve two purposes: (a) to expand the available roster of cars for each model to 30, and (b) by making these part of a separate series, you can select the GTB or GTE separately when creating an online or offline race (this was not possible in the original TC Classics DLC).
As a bonus, we've added a special 5-speed variant of the Puma GTE (as a separate model!) if you'd like to take the GTE to tracks with longer straights. The GTE 5S, as we call it, features a short 5th gear as well as adjustable final gearing.
We have included the original Reiza skins with this mod for the sake of completion -- no ownership or authorship of those particular skins is intended!
