Perhaps I'm not the first to figure this out.. but here goes:


after I took the nuts off, I squeezed Goof Off adhesive remover around the edge of the spoiler. Top edge first, opened the boot and then squeezed some on the bottom too - have an old towel handy as it will run.


Wait 15 minutes and voila! Pulled off without too much effort and cleaning the rest off the paint was pretty easy too.


Now - who wants to buy an R50 Spoiler? Cheap.
