Well...I don't think the American cars are really that dominant. The Viper just has too much torque and its very easy to spin out if you don't know how to modulate the throttle when turning. But comparing Viper to the Type isn't fair anyways. There seems to be less spin outs in GT3 compared to the older versions probably because of traction control. Yeah, you can practically create a track monster by messing with the settings. But it takes a lot of time so I just use a more powerful car to outrun the competition.
