Could take out the power steering as well if that's not considered a drop in comfort
Aircon system would be close to 14-15kg inc compressor, pipe work, extra radiator and fan etc

Ahh gotcha, thanks Chris.
fill tyres with helium
replace coolant with liquid hydrogen
remove doors that don't get used.

Or add a turbo =) then you can keep your leg.

that must be the lightest astra around.
You win @dutchy! I weighed all the aircon bits after I pulled them out of the corsa, 23kg

23kgs probably wont make much of a difference compared to the comfort it provides,
What about fiberglass panels?? anyone know if its legal?
my old s15 had a fiberglass bonnet (one of the few ADR approved ones in Australia)
but it also had fiberglass kit, and side wheel arches.
i Imagine it would shave a bit of weight, but now your sacrificing safety.

Bodypanels are part of safety, doubt you could replace them with fibreglass. heavy stuff that aircon system, i an surprised.
Now guy 27, you are going into extremes, helium in tyres... why not just shave the tyres to its minimum tread. talking about tyres, the old nylon (not steel belted) tyres of the bygone era were much lighter than the modern ones.
make the exhaust out of thin steel or even aluminium, that whole system is quite heavy.
Doing some research about the subject, the greatest effect on acceleration comes from reducing the weight of the wheels and brake disk rather than the non rotating weight of the body. The magic is that the tyres need energy to be accelerated to rotate as well as move forward. Porsche recons it is 1:7 but some general estimates are 1:4. That means that if you fit lighter tyres and rims and lose total of 20 kg, it has the same effect as losing 140kg according to the Porsche rule. that is quite serious effect and achievable. That's like removing one big bastard sitting in the back seat.
Another is the tyre rolling resistance. I have 205 Michelin Pilots under my vectra and it is hard to get moving by pushing on flat surface. My astra has Kumho ecsta 225 wide is considerably easier to push, and the weight of the car is not that much different. All tyre alignments are good as the tyre wear is even. I am tempted to swap the wheels over to see what the difference is.
All those boy racers whom fitted wider tyres than the specified actually made their cars slower!
Another rumor i was reading that GM US insisted putting thinner gearbox oil in its Cruze models to reduce losses and reduce fuel consumption. Europe did not because they knew that it will reduce the life of the gearbox. The rumour is that gearboxes in the US started to fail too early and some GM service places quietly replaced the thinner oil with thicker standard oil to risk manage the problem. The oil thickness was not that much different, 80 against 90W.
