Sorry if there is already a weight thread.
Real scaled weight not advertised weight with assumptions of mods.
I know its listed at 2955lbs and I believe that's the advertised lightest possible weight, I assume no option, except all the delete options, PCCB, no fuel but with oil and fluids? Anyone nuts enough to order AC delete yet?
I'm interested real scaled weights when you guys corner balance them, the options etc..
But also curious how light this (For todays standards) super light car can get..
Wheels..
Seats..
Exhaust..
Doors..
Frunk..
Roof..
Lexan..

The official weight figures I believe are for a car that has:
A/C Delete
Radio Delete
Smaller Fuel Tank
PCCB
LWBS
Lite weight Li battery
Fuel tank at 90% capacity
Wet weight (with fluids), sans driver.
If someone has a car configured exactly this way - that is the lightest weight Porsche could claim under EU directives.

^^ Thanks, I forgot about the Li battery!
The extra cost lighter options are:
LWBS $4730.00
PCCB $7400.00
Li Battery $2300.00
The rest is free, just a matter of deleting everything that can be deletd and not tick any boxes.
The MSRP of such a GT4 that ran out of fuel @ 2955lbs: $85,650 + above options = $100,080.00, just FYI.
I would love to see such a unicorn scaled.

To add to my post above, from memory: per EU6 Regulation, Porsche can quote the lightest possible spec. Per my list above:
AC Delete - 18 lbs
Radio Delete - 9 lbs
Smaller fuel tank - 20 lbs
PCCB brakes - 33 lbs (~$7.5K),
LWBS - 24 lbs (~$4.8K),
Li Ion battery - 30 lbs (~$2.5K)
Those are only options.
Fuel remains at 90% - 11 lbs, fluids are topped off.
So to OP – if one has a car with such spec it should be at the claimed 2955 lb curb weight.

My recent corner showed a little over 3300 lbs.
170 lb driver
Ext range tank full of fuel
Steel brakes
LWBS
PDLS
Fire extinquisher
All other options standard

You mean fuel is 90% empty, I assume?
Thanks!
I'm surprised that the 14.26 VS 16.91 tank reduces 20lbs!

Sorry - I think we typed at the same time. Keep in mind, weight of the tank is not just weight of the material, but they are measured at 90% full capacity (so adds the weight saved by the fuel itself)

According to 4carl, his car with 1/2 tank of fuel (extended fuel tank), iron brakes, and 2-ways was 3083 .lbs:

So you could work backwards from there when adding PCCB, lithium, stereo delete, A/C delete, etc.
CJ's GT4 has all the lightweight options except A/C, maybe he can tell you the true weight.

Seeing that I've owned my GT4 for almost 48 hours I thought it would be time to start taking it apart. First thing is I weighed it, came in @ 3083 my 15 CS PASM was 3048 w/ 14ways & ST 20s, my 15 CS X73 W/M seats& C20s was 3028. All were MTs.
The wheels are heavy R 55lb F 46, C20s 50&43, ST20s 54&44.
The Suspension is really well done. Both the F&R control arms are split. The whole rear is much more substantial. Better brake ducking but not as good as the gt3 that has a separate duct for the caliper.
Overall well done. Carl

Yes, you beat me to it and so I edited my post :-)
Great to learn this. So this means that 2955lbs is with an almost full 14.26Gal tank. That's about a 80lb difference!
So an ideal ran out of gas GT4 could really be about 2875lbs.
Thanks guys, very impressive numbers.

I was planning to have my car weighed for a second time next week so tell me, should I go in with 90% full tank? If anyone else will be doing this we should try to compare apples with apples. I recall vaguely that I was at 3025lb when I did my first oil change at 1800 miles and this seemed light for only having LWB's and PCCBs (I have partial leather, AC, and PCM).
Others were reporting heavier with similar specs. At just under 3000 miles now I have very little left of the original Dunlops so wonder if I've removed enough rubber to influence weight in any substantial way?

I think I am going to by an aftermarket Lithium battery because I heard there are better ones out there and install it from June thru Sept. I heard that those batteries do not like cold weather so I will pop it in for the winter storage and keep on charger.
I am figuring with my build I have to be in the 3020 range. It will be the lightest car I have owned
