A problem with all rear engine cars as the weight wants to come around to the front.It is not well known outside of Porsche circles, but the Carrera GT is very twitchy at the limit. Even very accomplished drivers have had difficulty with the car. It's beautiful, but not for amateurs.
Very sorry to hear the news...
A down to earth human being who not only loved shooting and cars, but a humanitarian. It saddens my heart that Paul Walker left this world young. Rest in Peace.
