WHAT A FANTASTIC EVENT!!!!! I was a kid in a candy store for 3 days, great people, and also GREAT info. Only downside was getting home, had to wait for crew. Finally got to our house at around 3:30a.
So for any of the tech geeks (like me) a few tid bits we got.
Front LCA's are only separated at the keel by 120mm (the lower LCA's are darn near 2ft long)
Frontal surface area of GT is 1.82 sqm, by contrast the 458 is 2.1sqm (the presentation over layed these, and also project Silver to show how small GT really is)
The COP (center of pressure on the car created by the downforce) only moves 10cm, wing up vs down, because of the active flaps in the front splitter.
And for those that understand the Spool Valve, the way its "active", is they rotate the valve to get the variability.
Benchmark was the 458, then the 675LT came along, and Larry Holt said, that when the 675 arrived, their "goal posts" were moved a good 40-50 yards further down field. But GT still beats it.
It is always good to go to Detroit / Dearborn.
