80 simplistic GTR Proto customisations in the form of .nfspscd blueprints. This is not a mod in itself, you will need a compatible car data editor as well. One has been linked in the readme. The readme also explains how to use the car data editor to make your own customised GTR Proto.
!!! The blueprints are otherwise stock and default to grip. Using them on existing blueprints will require you to re-upgrade/tune your car and/or change the racing mode in the data editor. !!!
