you need to "learn" how to drive an ST to get the best out of it,I know of one guy ,with a few mods has managed,quite easily to get just under 200bhp from his ST focus and can manage a 0-60 of 6.5 seconds,

As i said you need to learn how to drive them right to get the best from them,

I have one and they arnt that bad,i just miss the kick in the back side from the turbo charged cars
