Even heavier than I thought it would be, which was already more than initially announced.
Unless DK cocked it up while estimating the weight, instead of using scales.
I always love these user's guide from DK Engineering! This one is no different. So the dry weight in the updated technical specifications really was dry weight. Bit more than the 1086 kg wet weight based on some of the technical specifications. 997 kg dry weight + 29 kg fluids (difference between "show" weight 986 kg and dry weight 957 kg in old technical specifications) + 60 kg of fuel for full tank. DK Engineerings car does have the glass panel roofs which add 2.2 kg to each side so let's say 1090 kg. So it's around 10 - 15 kg off which can be lot of things I guess.
I don't think owners really care about these details tho since there is nothing else like it. Owner Woppum said around a year ago the CGT maybe a
but the T.50 is king of the ’s.

Something random but I'm interested what the actual wet weight of a McLaren F1 is. So with fluids + fuel tank. Most of the time on the internet I see it's around 1140 kg but I don't really trust non official sources anymore (sometimes you can't even rely on official) and I read once that it was 90% fuel. Official McLaren F1 press kit of 1992 says dry weight is 1018 kg.

I think you're forgetting that DK said their car had just under half a tank of fuel.
This is what their T.50 should weigh:
1026 (showroom spec) + 22 (exact 1/2 of fuel) + 4.4 (glass top) = 1052.4
Let's be charitable and say they measured it at 1,101 kg. That makes their car 48.6 kg heavier than the revised factory claim.
There's some good F1 weight info in these Pistonheads threads.

If I remember correctly Autocar claimed the F1 weight to be 1138 kg with half fuel tank in their famous roadtest. But I don’t know if they weighted it themself or just refeared to factory data.
I swear I heard a full tank in the video but you are right... I watched it back and they say just under half a tank of fuel. That makes it way more than the 10 - 15 kg that I said. I'm being pedantic as non-owner who will never own one because I'm not that wealthy but that's a bit disappointing.

Maybe their special Italian leather is just that much thicker 
That F1 Autocar tested was a prototype as well, IIRC.
It does seem like the way it works is, people only remember initial specification claims/targets for cars, and manufacturers don't give updates +nobody ever bothers to verify anything. Then if you question stuff you look like the biggest nerd/hater.

So 1138 with half tank is about 1170 kg curb.
Road&Track tested a F1 and messured the curb weight to 1288 kg, but this was a Ameritech version which was a little heavier (us market spec). The Japanese magazine tested a F1 and measured the curb weight to 1263 kg.
Car and driver quoted 2579lb (1170kg) in their test which I am presuming is the same from the Autocar test as they seem to be using the same numbers for performance as Autocar.

Yes, seems they have used data from Autocar and calculated weigth with full tank.
