Waiting for big Alex to set some things ..
we can use a few textures that I've modified and made to give a cooler look to this beautiful track.
Asphalt, new rubberized line and new braking signs for Jerez track
Copy the contents of the zip file into the jerez folder. In this way, new
textures will go to: ierez / skins / default ...
If you do not like the result, delete the files inside the folder, default,
and it will all come back as before.
