Right, let's cut to the chase. To use this correctly, you'll need ArtMoney with the trainer itself.
First off what you will be doing is going into the Aftermarket shop with the car you want to modify (Camaro ZL1 in this example)
Now start up the freeze trainer and lock up what part of the car you don't want to change when getting a hacked bodykit (We'll lock up the stock spoiler for the camaro)
Now keep the spoiler frozen, change cars via ArtMoney and get a hacked bodykit.
KEEP THE SPOILER FROZEN! If you unfreeze it without saving in the paint shop, you'll get the crappy spoiler on your car and not the stock one.
Now back out, change paints and save. Change back to your original car (CAMAROZL1) then there you go, you managed to learn how to use this correctly (For your sake you better have.)
This also works with removing spoilers, just freeze the hood and do the same steps above, but changing your default car to the Supra for a hacked bodykit.
