One small detail: The GT350R-C is not competing in the Rolex 24, but rather in the Continental Series GS class. Unfortunately, intake restrictors for the class mandated "balance of performance" index will attempt to keep her down a notch.
The Ford GT is competing in the Rolex 24, in the GTD class however. CGR needs to sandbag a bit, to avoid emasculation by the "BOP" rule.
However you are correct about the GT350R's aura and appeal. This car has spiked this long time Porsche owner's interest and have one on order. The first Mustang I have owned, coming to a track near you to terrorize my fellow Porsche buddies!
