I have used the included masks for the speed series of bodies ( not sure whic body it was). Yeah they did not work that good, but yes precut masks can be made to work. They need to be multiple pieces. Or, a small square of mask material can be included with the bodies, and you can cut your own.

I don't use the included masks with Parma Speed 8's either for the same reason.
