ZS Weight Reduction

I'm thinking of removing a few kg from the ZS, however it's a road car so it must remain as full interior including audio and cannot be "stripped out" so have to be a bit more strategic about it.



A few ideas I've had so far...



- Remove sun roof and replace with a fibreglass or carbon fibre bung. This would save almost 20kg total with all the mechanism and being right at the top of the car it would help to lower the centre of gravity as well. Simply bond a panel in place of the sun roof and then replace roof lining for one from a non sun roof model.



- Air con, I've asked about this before but was only given answers along the lines of "don't bother" or "why would you want to remove it?" the answer is simple a typical air con system can weigh up to 25kg!



- Spare wheel, a lot of modern cars don't even come with one, it can easily be put back in for long journeys, or simply replace with one of the "spare tyre in a spray can" type products. Save around 10kg.



Already that's a potential saving of around 50+ kg.



Another potential weight saving would be light weight wheels but in my case that would be off set slightly by the added weight of the bigger brakes that I have just fitted. Reducing unsprung weight is said to be very worthwhile though so is certainly worth considering.



Anyone else got any ideas?
