Isn't the Ford GT even more twitchy?
It won't probably reach the top speeds of the McLaren or NSX (however, the NSX should have a slightly higher drag and about the same HP, so?), but the design of the car generates lift at high speed.
As on
Mulsannes Corner, the GT40 generates 100 lbs
lift @ 150 mph, with 525 lbs of drag.
The GT has the same shape as the GT40, but is just bigger, so it will generate the same lift at lower speed.
So it should be as twitchy as the NSX or McLaren. Probably less force feedback in the steering wheel, because the front wheels are lifted too, but it should be a lot less stable! Could you experience that?
To compare : the 1997 McLaren Long Tail generates 1234 lbs
downforce @ 150 mph, with 561 lbs of drag.
