A photo of a Honda Accord BTCC shell gives us a great opportunity to observe the way that the load paths are fed through the cage from the front to the back of the chassis. Loads from the dashboard area are fed in two directions: down to the base of the main hoop, and up to the top of the windshield and then down to the middle of the main hoop at the driver's shoulder height. This path then continues down to the rear floor pan to pick up subframe mounts. Note that the entry for the driver has essentially become "diamond shaped". Also, although there is no diagonal in the main hoop, there are two mini-diagonals which extend from the middle of the main hoop down to the center of the car on the exhaust tunnel. Check out the "NASCAR style" bar which extends from the upper left side of the windshield to this same point at the center of the car on the exhaust tunnel. Very few European race sedans use this type of tube.
