theres a 10-15% correction factor on speedometers. You don't notice it at 50, because thats roughly 5mph, but at 150, your stock speedo is way off.
I personally dont see the big deal of a car that can do 200mph.
Everyone knows about speedometer error. It's so common that no one mentions it. It's like a riced-out Civic with altezzas. No one says that Civic had altezzas because it is so commonplace nowadays. Hell, it's a lot more uncommon to find a Civic without altezzas!
Oh and, by the way, at 65mph my STi has a 4mph error, at 105 it has a 6mph error.
