Someone just laid the Feb '10 Car and Driver on my desk because it includes a S260 track performance comparison (at VIR). Turn 1 is titled "horseshoe" and is 180 degrees. They go on to list the various cars performance in turn 1 expressed in time and G force. Much to my surprise it showed the S260 only achieving .91g. A freakin' Mustang did better at .93g.
