You can take the tar under your car that protects the body it weighs about 200 pounds but then your bottom rusts out. I removed my spare, stock sub, the wood florbaord piece, the carpeting, entire back seats, paneling, just left one lightweight sparco seat in the front. The rear of the car lifted up abotu an inch and a half and the handling was bad, the car rolled more and i slipped when making sharp turns easier. higher center of gravity... also removing your gas tank and relocating a smaller one to the engine would provide you with more front traction becaue the more weight on the front wheels the less slippage when u start or changing gears. removing all of this didnt take to long, it toook longer to put it back on. Once i modify my car more im def going to strip it again.. also removing the power steering belt would add a bit of zip to your car for a free mod..
