Extent Or Your Cars Weight Reduction

I would love a light car, but I hate the looks of a gutted car. My all out drag car is ladder bar and weighs right around 3000. It still has door panels, dash pan, gauge and carpet, all glass. I even ditch the hood pins for the factory hood latch and stuck in a factory gauge cluster. Yes weight makes a difference and every little bit supposedly helps and I'm sure it makes a difference. But I have tried drag front tires vs M/T sportsman and seen no difference in E.T. I've also tried tubes and no tubes in rear slicks and haven't made a difference. I didn't weigh the tubes, but I run a 30x13 tire so the tubes aren't super light. Save the weight where you can without totally butchering the car, but if you want to go fast, just build a larger motor.
