This decal is sized to fit the Porsche 991 GT3 or GT3 RS rear wing (depending on which version you want). Add this to go with some side side decals or go with just the wing decal for a clean look that gives your 911 a very distinctive look from above. We've made this version with a curve to flow with the wing shape. When ordering, please specify if you want the wider GT3 RS version or the shorter GT3 version. There is a location to leave us a note  in the checkout. Just mention the version in this note location.
