Extract the paint.tga into your Sierra/Viper Racing/config/Paint folder, 
Extract the warhead.car into your Sierra/Viper Racing/data folder,
go to paint in the game & inport.
I have also included a warsetup.jpg with the zip file, its a setup for the gearing & 
so on, start with that setup & tweek it from there,
or if you dont wont to to use this setup make sure you set the cars setup to default
in the game or it may not move.    Ashes48
