Sweet! Yea, I agree. I hit 160mph about 2 weeks ago, and it was VERY stable and smooth. Didnt take long to get there either!
I took some pics of the F on my drive out to west texas.

Pushed it through some crazy turns and the car handles like mad, it is rediculously stable at high speeds, i hit 160+ multiple times on I-10 and it felt well grounded. Was doing 100mph on turns that were advised at 45mph and the car felt great. The drive from Presidio, TX to Lajitas, TX onto the Chisos Mountain Lodge is amazing. There are some sharp turns rated at 15mph which are a stunning...i did oversteer once, however did not go off road.
Unfortunately, i did not have a camcorder mount and my friend who was holding the camera for some of the sections filimed mostly the dash!!! I am going back for sure.
Cheers,
