manogh said:10 kg drop in weight is definately worth it...esp when one arrives at the track....but only time will tell if its the best way to lose 10kgs...lets see what the future unveils for us all.
If you were looking for the lightest specification available, you want the lightweight seats, lightweight headlights, delete air con, delete audio system, without clubsport (i.e. ditch the cage - it is heavy) and then the lightweight battery. While 50-60kg lighter, you will have then spent over £111k on something with a crippled residual value though...
(What use and RS without cage and harnesses, but even if you left those in, the lack of air con has been proven to make then unsalable at anything near book price in the past).
Oh - anyone else notice that on the configurator the nasty logo on the front right wing is not there? [The one on the left rear still is though].
