Pretty simple, finally, after many weeks, this is the actual legit MyDriver S2 Mod Pack that I used in every video for use of your own (obviously altered and neatened up for easy install)
I can't obviously give you the race-by-race team upgrades and evolution, so I've chosen a race mid-way into the season and given you the performance of all the cars at that race. (It's Belgium if you were wondering )
This mod will place myself "aarava" into your grid driving in the Mercedes. So if you want to change that to someone else, you can edit the language file and change the "nico rosberg helmet" from my design to the one you desire yourself.
To install, just drag and drop all the files into the F1 2015 folder, as usual, make sure you backup the Vanilla files in-case the mods mess up, but they shouldn't if you just drag and drop nothing more.
99tss, I used one or two of his liveries from his 2016 mod
Danger88, I've used all of his excellent correct sun mods
