I have a buddy with a GT500 and he wants to take it to a track (The Streets @ Willow Springs) I am concerned that he is going to overheat fairly quickly under such extreme conditions. Has anyone driven their GT500 on a track such as that or have any idea how many laps he might expect to get in. For those who do not know, Willow Springs is around 100 miles north of LA in the Desert Mountains. Thanks in advance for the help...
