A book about a car I love and aerodynamics? whats it called?


Honestly mate I can\'t remember - it might have been something I read on the net.  It had all the figures and compared to several other cars too, it was quite in depth with figures for all sort\'s of areas including all the different rear wing\'s and the 2 general front splitters - there are not that many car\'s that are more slippery than the FD.

I\'ll rack my tiny brain to see if I can remember where it was I read it.....

If they do it with a monster aero kit fd with canards hanging off it everywhere. Maybe that would be better.

translate this. then compare the figures to the standard car.

this test also measures different things. like reductions in Lift and Drag in each direction.

interesting to note, that a well set up car isn\'t really that much slower, its just that a car with aero is easier to drive and gives more feeling.

But then again it is 2 seconds a lap... haha.

Hayne book called" Competition car DOWNFORCE" by Simon McBeath

My Thinking:-
Think Shark with close mouth=smooth=fast!
Think Basking shark with mouth open=drag=slow!
