Ok, so I have had an internal discussion in my head regarding if the ST/RS are the quickest, or fastest cars on tight backroads. I have driven Corvette's, Porsche GT3's, etc. These cars are no doubt really fast cars. But as far as a backroad car goes, I really believe that there is nothing faster than a Focus on a backroad. I have the Ford performance calibration on my ST, and it just makes the car haul on a backroad unlike anything I have driven. I think the main reason for this feeling is because it is a small and light car, and also I think you can use ALL of the power in most situation, whereas in a high performance car like a Vette, you can't unless if you want to end up in the trees. What do you guys think?
