I'm not too sure since I don't have a jato, but it would seem like you would be able to as long as you don't take out any of the screws that hold the main chassis part together. This will make your car much weaker and prone to breaking by taking those {seemingly un-important} parts off.

To tell you the truth, I don't think you'll be able to tell much of a difference between with and without the parts on, so I see no point in taking them off.
