I think there should be a discussion topic and then a locked update topic where after every race/test the changes to the car are logged along with brief descriptions and a link to the point in the main topic where people discussed it. That way you have a nice small thread for users to browse all of the updates and new tech, and an actual discussion topic for that thread.
IMO, this idea isn't that much different then our articles on the front page and the car threads in the forum. But again, we'll consider it.
Feel free to put it on the website once I post it on the Forum. Saves hiring someone.
