Does anyone know how much mass you can strip out of a Copen? I've searched the forum briefly but couldn't find a thread about it. I'm working on a hair-brained idea of turning one into a track-day car as I like the challenge of making one fast enough to keep up with circuit traffic. I know there's scope to get the power up to around 120HP with a turbo upgrade etc. but for best effect I need to get the mass of the car as low as possible to make the most of what power is available! So, how low can you go?
