Remove the rear two battery packs. Then put them back in afterwards :)

It should only be a mere 60 kg or so overweight if anything.

If it is overweight what can you do to make it pass?
More seriously, my understanding is that you might:
  • End up with a lower luggage capacity
  • Have to register it as an n-1 seat vehicle, where n is what you tried for last time (might have to remove seats and/or seat belts)
  • Keep the same luggage capacity and seats, but beef up the brakes (e.g. larger rotor and pads) and possibly add some more structural support, as designed by the engineer. The brakes may need a fade test.

A Google shows Gvm is 1565kg
People and luggage is 81.6kg per seat
81.6kg x 4 seats = 326.4
1565kg - 326.4kg = 1238.6kg
Standard weight is 1060kg - 1340kg depending on model
You got 1100kg when you weighed it and presumably you are also going to ditch the spare tyre now.
Looks like you have some reasonable weight to spare.

Correct, 1100 kg with the spare tyre and tools, and a full tank of fuel. So we should be pretty close to original tare.

I had a friend knock up a couple of stainless steel fittings designed to perfectly match the 7/8" aircon male end.

Next step is to braze these on with silver solder. One shot - no pressure...

Silver soldered and re-plumbed. Ready for some aircon hoses now! I should read up on the compressor and make sure I'm about to fire it up correctly...

Today I pulled the bumper off and replaced the failed windshield washer pump. A sure fire way to fail the inspection if you ignored it. Luckily all the auto stores had some workable options.
I also finished the single phase 32 A EVSE. Literally just assembled it according to the instructions and it just works. I doubt the thing will see anything other than being plugged in for 6 hours and unplugged later on. WiFi? Nah. It's a glorified power point.

Monday afternoon I will drop it off and the new A/C plumbing will be installed and re-gassed the following day. Francess picks the car up on Wednesday and will drive it around before getting new tyres on Friday. Then, with new hoops, new windshield washer, air conditioning, inertia switch... more compliances than you can shake an NCOP14 document at, it will go to the weighbridge and then around to the engineers office the following week, just in time for Christmas!
