Porsche 934/5 Flame Thrower
During the 1976 season, several Porsche customers modified their 934s to Group 5 specification and Porsche catered to their needs by producing a batch of 935s for the 1977 season. These were still not allowed to run in the IMSA series but the door had been opened for the 934. Accordingly, Porsche built a further ten 934s with wider wheel-arches and a much more substantial rear wing. Known as the 934½, these were raced with great success in North America.
