With double sided tape a scalpel and LOTS of patience
i was thinking the same but think ill probably get a sticker made up like these ones :- http://www.cliosport.net/forum/showthread.php?606343-Original-182-and-197-Rear-Decals
I did the diamonds and the Clio badge cos that just clips out, but i found it easier to push it from the back as not to break the clips... I'm just going to remove the sport and Renault badge. did the bullets too, they come off easily.
