just because it is Prodrive doesn't mean it is WRC.
prodrive is a company that makes quite a few things. and vehicle dynamics is one that they have been working on for quite a number of years.
I personally don't like stability programs because even in the off setting they still take some control.
That system seems like it would mesh nicely with an STI driveline, but it would need to turn off completely to make me want it. still I dislike stability control.
if it is something i would turn off while autoXing or rallyXing then I don't want it when communting. I use AutoX and RallyX to learn the car. if I learn something and then it reacts very differently on the street I am in trouble.
