It is not outrageous when Ford advertised this car as the most track capable Mustang ever and a standard GT will outlast it at an open track. 15 minutes until limp mode is unacceptable. It has also been shown that a tech car without cats still overheats the transmission.
It never advertised that though. They said the 350R was!
Did you buy a 350R?
Does the 350R overheat with just 10 minutes on track?
