An
excellent shot of the '01 R8's nose diffuser, shot at Mosport
2001.
It is changed somewhat from '00.
There appears to be more kick-up to the outer diffuser sections next to
the wheels. Also, the strake in the outer section has moved
closer
to the front wheel and its orientation is more parallel with the
car.
Note the lower A-arms are running in the diffuser area.
Note
the center diffuser strake leading edges are angled inboard towards
centerline
as on the 2000 car.
