I did my rotors calipers this summer. Like other said, there is just some bolts to remove. Its easy.
I sandblasted everything (rotors and calipers), did two primer coating and then two paint coating. I did not used high temperature paint.... 3 months so far and the paint is just like when I sprayed it. I don't know how it will handle the winter... they put lots of salt here !
if you have any question, just ask !
