hello rower, I do not know if my translator has translated correctly: that it is a scheel is clear. yes it is the same model as in the 911R (without rivets) I found it worth mentioning, because the seat is on a large recaro console (it was only from model year 1969 - so fits the lwb, which I never as a base basis for a bucket have seen) in the 911 R, this console was certainly not yet, because at that time not even existed. I hope I have expressed myself understandable?
That makes sense! I was looking at the photo of the most original R and comparing.Originally Posted by recaro
It’s interesting that apparently the 911R that won the Marsthon the prior year in 1967 also had aluminum bodywork unlike most R’s
“ The '67 Marathon de la Route winner (shown above) was the third of the four 'prototypes' - R3 - which was fitted with aluminium front wings, bonnet & doors (skins).”
Can anyone else confirm that? Or speculate why?
Copying my post from another thread on the lightweight thin metal body shell of the GTS and that it is apparently lighter than a 911R.
Factory documentation indicating that the lightweight GTS’s used a thin metal shell. Plus aluminum front / rear bumpers, door skins, engine and hood deck lids, and front fenders/wings. Even things like roll bar and headlight buckets were aluminum.
Note that fully loaded for racing with fluids and tools they were weighed at approximately 928kg racing weight. (Actual weighed GTS’s were 928-930kg - full fuel, oil, tools, spares included as ready to race) but I suspect they state 940kg on some docs as it ties into the homologation weight of the dry 1969S). Subtract the 72kg of fuel and that’s down to 850kg. Then subtract oil and tools and spare tire and spares, and these were lighter than the 911R which is misleadingly quoted with no fluids or tools etc. (and none of which actually weighed the 810kg that is often quoted).
The lightest 911 model made.
Here is the factory document (and the list of changes goes on for a further page; highly customized )

Very helpful. This may have solved the homologation low weight question for the 69S.
What is the document source?
Internal Porsche werks document. Post race write up with full description of all cars and their modifications, and race results (number of tires used, lap times, fuel used, part evaluation, things to be changed for future use, etc etc)
For the 911GTS . . .
A 911R --- scaling @? . . .
Where are you getting 638kg for the 911r?!
The most often thrown around number is 810kg dry, but I saw actual numbers that were much higher.
Collier has the best one out there, and they quote 822kg dry (no fuel, oil or parts)

Hence the GTS on an apples to apples basis is lighter.
Of course, a special customer could order a 911R; the GTS was pure factory built and factory raced. No customers allowed!

Must be with its engine out. I just don’t believe it. Where do they find another 200kg to remove?
