I can't help to wonder this.
Now searched some images of #21R what I have collected this forum and so on; seems McLaren has done the change to the front aerodynamics?
It was made 2002-2006 when McLaren rebuild it and after that there is that large air intake before front fender.
British GT it wasn't there, but 2009 in Modena it was there. Also I have some "museum" images taken from this forum, where is #21R is some kind of show room with other racers (including orange shorttail GTR which is #07R or #11R? or is it?...?) and the air intake is those images.
1. Which year it was there in "museum?"
2. McLaren did that large air intake then? Or did it?
3. Why it have been done?
4. It isn't there in 1997 or British GT race images, but suddenly after McLaren? completely rebuild, it is there.
5. Anyone know anything about this?
