I would first like to start by saying that I have been visiting this site almost daily for about a month now and I really enjoy it!
But the reason for the post is these new vents that have appeared on the nose of many of the '06 chassis. I can't figure out their purpose, I apologize if I missed this topic earlier. The only conclusion I can gather is that they are for cooling the shocks, or the tanks of fluid that can be seen when the nose cone is removed.
