From what I recall reading, the new GT3 has a published weight of 1395kg. Is that the lowest weight (car with PCCBs and carbon seats)? or w/o those options? The PCCBs reduce the weight by 20kg. I am not sure, but I assume the carbon seats by another 20kg or more.

The published weight is without both PCCBs and bucket seats. You are correct about the bucket seats saving 20 kgs.

We all struggle with the Porsche AG published weight data. It used to be noted that it was for the base model and was "curb weight", that being the vehicle ready to operate with full load of fuel, no cargo, and no humans on board.

The debate would then proceed to was that for RoW specification base cars or specific to North American base versions (for example, we usually have AC standard and for RoW it is optional).

Currently, I think it is safe to guess that since PCCB is an option that mass reduction is not in the figures. Seats??? whatever is standard in the base car for that part of the world. North America will only get heavy or heavier seat choices from the factory.

Published 997 GT3 curb weight is 3075 lbs or 1395 kg but I do not know how much fuel that includes. We have discussed the fuel load on here before, some thought it was 10%, others 90%.

Thanks for the info. Now I suppose the US mandatory sunroof puts back 50 lbs. As much as I'd like to see the sunroof delete as an option, I don't think there is much chance of Porsche certifying cars w/o the sunroof for a few hundred sales per yr. Hard to believe Porsche won't put a sunroofless car together while BMW goes to the trouble to put a CF roof on the M6.

You see my point about the 1395 kg value and not knowing what that really goes with. Plus is that North America or RoW spec car weight?

North America 997 GT3 base car has sunroof mass and AC mass, but RoW base car does not.

I used to have a Porsche document explaining every factory vehicle weight and alignment specs. PCAG thinks of curb weight as 50% fuel load. They go on to note that there's no "average" weight driver, that various factory option wheels can vary by 5lb+ per corner and "other options" might raise or lower the vehicle weight.
I don't think they treat those published weights too seriously other than to give a number to DOT or TUV or whatever red tape factory.

1,395kg is dry weight as far as I understand, i.e no fluids at all.

It does include all standard Euro equipment - and A/C is standard. The buckets and PCCB would save 20kg each.

Hope this helps.

Me thinks we will have weigh some North American 997 GT3 to know.

3241, if true..is kind of porky for a GT3. me thinks PNA dropped the ball on the US GT3 sunroof and all. Im changing order to Turbo. If my GT3 is watered down might as well not get it at all.

I've data from several US 996 GT3 with different configurations. A full tank of gas weighs around 100 lbs (6.2 lbs per gallon and 16.6 gallons fuel tank). The 997 GT3 is coming with the 17.7 gallons fuel tank.

My car came at 3133 lbs with steel brakes, A/C and 1/8th of a gas tank.

A recent German magazine test listed the Euro 997 GT3 at 3220 lbs. It was 110 lbs heavier than a Cayman with a 4.1L engine. That GT3 didn't have a sunroof, and it had the Recaro Lighweight seats.

My expectation is that U.S. 997 GT3 will be in the 3205+ lbs range from the showroom with practically no fuel, 3315+lbs with a full tank of gas, and 3425+lbs according to the Euro standards for 1/2 a gas tank and a 75Kg driver. This is assuming steel brakes and A/C.

The $9k PCCB option reduces around 37 lbs from the 997 (42 lbs from the 996).

I don't know the weight on the 997 stock seats, my 996 stock seats came at 52 lbs each, my GT3 Recaro seats weigh 28 lbs each (includes mounting hardware). The CF version for my GT3 Recaro seats are 2 lbs lighter, so I expect the CGT/Euro 997 GT3 seats to weigh around 26 lbs.

Regardless of being 100+ heavier than the 996 GT3 for the U.S version, the 997 GT3 will still have a better power-to-weight ratio. That's assuming the 996 GT3 really has 380Hp and the 997 GT3 really has 415 Hp.
