The roofs like that as the cage must be welded in so its the only way to get it in. The old evo was banned from one rally as they did not weld around the top tube because the roof was in the way lol. M-Sport cut out little sections of the roof, weld the cage and then repair the roof. FIA wont allow carbon roofs in WRC Group N spec. Plus the American subaru is a bit of a joke, you cant beat prodrive for scoobs!
