I checked out the Honda Racer and they dont have this. But on the Super Aguri
If you noticed on the chimmney they have a attached flip up to it, Im guessing it help's moving the airflow to the rear wing? Also would this help to move the hot air flow to the rear wing of the car?
Sorry for all these questions with pictures, But I find so many differences to the cars, I hope you guys dont mind this? If you think it seems like post whoring tell me and I will stop
