What exactly is a 964RS 3.8L?

I can only assume that the car I saw had special ordered hood. They did use the carbon/Kevlar hood on the 92 turbo correct? If so it must have been fitted to the black RSR i saw. It was very obvious that the hood had a weave to it under the piant just like the body panels on the Ferrari F50. I recall the owner of the car claiming the RSR cost him over $200k from the factory back then.

Paul Frere in his book Porsche 911 Story describes the car on pages 302 and 303 of the 7th ed.
Here are points of difference to 3.6 Carrera RS
This appears to be exactly as I saw in Ludigsburg in 1993
Here are points of difference to 3.6 Carrera RS

Here are more pictures I took in Ludwigsburg 1993, note the Turbo body, 9 and 11 inch 3 piece wheels, Turbo S brakes and individual throttle bodies on the engine just as in Frere's book:

Yes the RS 3.8 was fitted with Turbo brakes (928 pads) and with the Turbo wheels for the road version. However for the body section here are the pages related to the body out of the Porsche Motorsports parts catalogue. Either Paul Frere or Porsche got it wrong in this case.
The first page says what the Basis of the body is and the second page provides the parts which were made for the body of the RS 3.8 which were not used on the 3.6L Carrera RS.
Ciao,
Adrian.

If this is so it must be a technical issue with the FIA, the car clearly has a Turbo body shape. I wonder what is the easier way to go, add flares to the 3,6 RS body or start with a Turbo body and do the seam welding etc.
Note that the list you provide shows aluminum doors as Frere said.
Arn't the 3.6 Turbo wheels 8 and 10 inch wide front and rear rather than the 9 and 11 of the 3.8 RS? My photos show wider wheels than a 3,6 Turbo.
Do you mean that the rear brakes have 928 pads, is this what the Turbo S has? It looks to me as though the rear caliper in my photo is a normal 3,6 Turbo caliper.
The front brakes in my photo are clearly 3.6 Turbo brakes which do not use a 928 size pad like the 3,6 RS did in the front.

I should have been more specific. The RS 3.8 wheels have 965 part numbers and yes they are 9x18 fronts and 11x18 rears, but you can have the optional 17 inch wheels as well. The offsets are also different at the rear because the RS 3.8 uses the Carrera 3.6 rear setup. This is all described in my book in which I used the parts catalogue and a real 964 RS 3.8 as my references.
I don't know what the Turbo S uses for brake pads maybe somebody can find the special parts catalogue for it and let us know. The RS 3.8 uses 928 pads on the front and 964 Turbo (965 part number) pads on the rear.
The pages posted above clearly state where to go look for the body part number and it even says they use the same picture numbers in the Carrera RS 3.6 microfiche.
Any claim that Porsche Motorspsorts used a turbo body and seam welded it to make the RS 3.8 Turbo-look body is not supported by any paperwork. In my opinion such a conclusion would be similar to other unfounded claims about other special Porsche models made on this forum and elsewhere like seam welded bodies were used for you know what? And special hand picked engines were used for you know what? But white ones go faster.
Ciao,
Adrian.

I can't quite read the print on the page of your scan, so can't see if it says 3,6 or 3,8 so that is the problem I had.
The 3,6 Turbo uses a 928 part number on the front pad since the late 928s used this caliper with a 10 mm wider than RS 3,6 pad as well.
I bet the RS 3,8 and Turbo S used the same brakes as the Turbo 3,6.

The RS 3.8 front callipers are 965.351.425 (426).10 and the rears are 964.352.421 (422).80.
Front disks (rotors) are 965.351.045 (046).00 and the rear disks are the same part number as the Carrera RS 3.6 uses.

PS: All this will be pretty irrelevant when looking at the race car versions especially in the series where single wheel nuts were permitted. The data above is for the RS 3.8 basic and clubsport versions which could be road registered in some countries. By 1995 the 964 RSR had been somewhat further developed and I don't have the Porsche Motorsports catalogue for them.

Of course I found this thread out doing research on the RS. What a beautiful car.

I still think the power package rule makes sense. However, the 993RSs should be bumped up to B too.
