I’ve been asked by a few for the RS logo.
Here’s a list of a few websites where you can order them.
TTRS Grill Badge
Audi RS large brake decal Chrome Silver Red
Last but not least, I have the actual Adobe Illustrator file. Using this file, you can have it printed as stickers or even embroidered on clothing or car parts. This site won’t allow me to post the file, but contact me and I’ll forward it.
Ciao for now!
