A local track buddy was recently down at Thunderhill with the Shelby kids for a track day in his (new to him) 2003 SVT Cobra. He completely swapped out the rear suspension for some kind of race setup. He recently commented that it drives much like his old SCed E36 M3. As an aside, I think his speed is a little down in this video due to elevated oil temps (an oil cooler is going in soon!).
You gotta love that SC whine.
