Well no matter what they do testing is always done and we never know how much is being done since they have both indoor facilities and out door facilities to use.
My guess when it comes to being track oriented is they might pull some DNA from the new Viper which was far more track oriented than the last one and any before it. It just doesn't help that it got low sales.
They make take the coil-over suspension setup and maybe adjust it to be not as aggressive. But still provide the height and shock adjust-ability. The aero on the Viper ACR especially helped with how amazing it was on the track. Extremely functional and effective. But the Trackhawk won't see any of that stuff.
