Its kind stupid to drop weight when the car is your everday car. If you want to seriously drop weight remove everything on your interior and everything in your trunk. Take it down to the paint. If those 20 lbs of a spare tire and jack are gona make you win a street race againt a honda and not get anything from it then go ahead. But when Im drving throuhg no mans land and get a flat and "WHoops my BMW road side assistance is outa date" I can change my own tire.
Oh yea take out your entire dash and center consol and get manual seats. THe power seats take up alota weight. And remve your sunroof casette and leave the glass in. Then go under the car and remove all the heat sheilds and plastic covers. Then remove your ac, power steering, washer fluid containers, and every piece of worthless plastic in your car. Then you can go a beat that honda!
