How do you make a race car out of icing?

Answer 1

If you're trying to make a three-dimensional race car to put on top of a cake and your icing keeps collapsing, then try using something with a bit more structural integrity like fondant or marzipan instead.

If you mean the question literally, I don't think we can help you.

Answer 2

sorry to disappoint you but for main FIA approved racing you can't use a homemade racer but you can still build one but you can't used it in official races
