HELP - Weight saving bits

Hi guys, I am interested in saving a little weight from my S1 exige. Can anyone point me in the right directions to what to tackle first. I have looked at the TMR wheels which seem to save a fair bit, whats the best way to shave a few kilos ? Are the carbon body panels worth the money ?

Finally, who has the lightest S1 exige and what does it weigh compared to the standard car ?

Any help much appreciated :O)

The TMR wheels would be a great weight saving - unsprung rotating mass, therefore great benefit to performance.

Here is some general info on where weight can be saved:

If it’s an Air CON car that has to go if you’re on a weight saving drive.

Lightweight battery?
Motorsport roof and engine cover (they’re both high up weight, worth lossing)?
