Do that a few times and it makes a big difference, especially on track.
Lightweight battery and seats would help a lot too.
I agree 1% is 1% of everything but we were actually talking 0.68% without the driver and fuel.
I guess I use my stereo about 90% of the time so the thought of removing it to gain an inperceiveable improvement in performance wouldn't be worthwhile for me.
Chuck out aircon, removing the seats and going CF bucket would make a difference, physcially moving the battery to the rear and fitting a drycell battery would gain you far more kgs. Removing things like motors for electric windows etc, take out the door cards, headlining, carpets, sound deadening, remove the airbags, remove the underseal, swap glass for plastic, wheels getting magnesium alloys, swaping components like alternator, radiator for race spec lighter components there's got to be a whole raft of stuff.
