They are Plastic, and so are the factory ones on the car....I have pic's on my profile of the ones on the fenders....if you go to the dealer the same emblems are almost $30.00 each..

Yes, it is the same as the trunk emblem..I purchased mine at latemodelrestoation.com They are $14.99 each and are from GM in a GM parts box..can be purchased single. I changed all my emblems from the red to the white to match the stripes...also removed the camaro letters from the sides and replaced them with the "SS emblem
