More power.
My car has a curb weight of 3100 pounds and thats before all the crap ive instaled. Some parts lose weight, most dont. But if you have the power to back up that huge a__ then it goes un-noticed (until some 2500 pound civic hands you your butt out of a corner, but come on, how often does that happen).
Ive found the a crisper suspention will make the car "feel" lighter. I just cant see chopping Lexus, just not my idea of a lexus.
Ive been test driving my buddy's sc3 auto and to tell you the truth i was surprised how light it felt compared to my gsx. not LIGHT but lighter than i expected.
Jerry spring final thought. the fastest cruise ship in the world has 4 engines at 13,000 horsepower (travel channel). Who knows how much the damn thing weighs.
