"We built the rear spoiler out of foam," says Year One's Keith Maney. "When we finished, we put tape on it to give it a solid look. We worked it into the shape we wanted, and then we made a fiberglass mold out of it. We actually molded the spoiler on our Forza car while the yellow one was in paint, so it didn't fit perfectly when it translated over to the SEMA car. If we decide to sell it, buyers will have to understand that it may need some tweaking."
