you can definitely get it down to weight. mine is so light it needs to carry a spare tire and 100 lbs of ballast with an approx 200lb driver. stock gas tank still in. all sound insulation removed, as is most all of the interior. i am actually looking for parts to put back on the car to get UP to weight. that driver was the previous owner, I am about 15 less than he was....:-)
