After some research I decided that I liked the look of Revo's Stage 4 option for the Fiesta ST180. Just to make sure of my full options I decided to have a look on their official site only to find that it isn't listed. Not only that, even Stage 3 isn't listed as an option, only Stages 1 and 2! It seems that you can only get Stages 3 and 4 via secondary dealers, which is extremely odd. On top of that, they don't show the full list of hardware needed for upgrades. Am I missing something here? Why aren't Stage 3 and 4 listed on Revo's official site?
