Whats the point of having 650hp, and I'd assume 600ft/lb torque, if you don't have the traction to use it...
This is why I take stated 0-60 times with a grain of salt, especially for RWD and manual vehicles. If you shift wrong, or slow, or its a little wet out, or you don't have racing slicks on, etc all will put you well under the manufacturers stated time.
Meanwhile I'm over here getting 3.2 the first day I got my car. Feels good!
