Hey, rice eater, so you want to make the car lighter than it already is? The only way to do that is to tub it out, and I mean strip out everything. Passenger seat, rear seat, take out the headliner, the window motors, the radio and speakers, the wiper motors, headlights, tail lights, and so on and so on and so on.

Basically, your car will not be street legal anymore. You will have to trailer it to the track or dragstrip.

The S197 is heavy by design. Making it lighter requires rather drastic measures.

How to lighten it and still remain street legal? You can't. Trade it in and buy a deathtrap Smart Car if your want lighter.
