Came across more problems with meh game, so here's the finished half of my "Special Police Pack". Cars are kinda based of the Metro Transit Police Dept from DC,VA, and MD.
Features:
Tahoe and Charger SXT
Extra Rambar w/ lights, extra seat organizer
Breiht Lehgtz
Installation:
For RDE users: Install into update.rpf\update\x64\dlcpacks\rde\dlc.rpf\x64\levels\gta5\vehicles.rpf\
Non-RDE users will have to rename the cars to whatever you want, then place in the latest patchday: update.rpf\update\x64\dlcpacks\patchday9(or 10)\dlc.rpf\x64\levels\gta5\vehicles.rpf\
The sirensettings is 1, so change the .metas accordingly, if you need to(Probably won't at this point)
To edit handling for the tahoe:
Go to the necessary vehicles.meta, and change the handling id of the slot your using for the tahoe. Replace the handling id with "baller" or "baller2"
Please report any bugs. I haven't gotten a chance to test the cars in a while, but I don't believe there are any problems.
