I have a document that shows the RS Club Sport model was lighter than a stock RS @ 1,100kg empty weight. That is close to 993 cup. Other than the weight the CS had plastic 1/4 windows. All the other specs look the same in terms of G50/32, brakes, flywheel. No airbags, radio, a/c in the club sport. Does anyone have any "dependable" full documentation for these Club Sport 993's. Club Sport had one wiper.

I am back dating my 993 to a club sport for PCA Racing and am now down to the cheap stuff I think.

The front and rear spoilers are quite different. I could hazard a few more 'guesses' but you asked for 'dependable' documentation

Dbltime

The body work is exactly like the 993 Cup. The RS could have the same spoilers as an option. I think we are all in agreement on that much. The RS & RSCS mechanicals seem identical. Beyond that the important issues are "air jacks", weight and fuel capcity.

A complete "official" standard/option list would be what I need for my log book.

Bill,

Looking at the technical information manual for the RS (M002), which also denotes differences with the RS CS (M003) there seem to many small differences throughout the manual. Some that are listed are:

RS had G50/31 and CS had G50/32 (swiss RS version had a G50/33)

Safety:
welded in cage,
suspension brace,
race seats with 6 points,
cut off switch next to ignition and by battery,
fire extinguisher

Body:
rear wing,
front splitter,

Interior:
no trim panels or dampers,
interior painted color of exterior
sun visor only on drivers side.
No dual mass fly wheel (torsional vibration dampers are used)
Vented clutch chamber
tranmission mount shore rubber hardness is 75 not 60.
Optional driver side airbag only

Engine:
RS and CS same engine at 3744cc displacement (M64/20) with various upgrades from stock engine type M64/05

Heating:
No engine heating blower
No air intake from engine


That is all I could find in the manual of the differences between the RS and CS. Of course there are numerous differences between the standard 993 and RS.

Hope this helps.

Kary, That helps a bunch! No mention of the weight? Any chance you could fax or email me the page(s) so I don't get DQ'ed again next month.

Thank!

Bill,
The curb weight in accordance wih DIN 70020 says:

front: 495kg / 1091 lbs
rear: 775 kg / 1708 lbs

Total: 1270 kg / 2800 lbs

There is no mention of the CS weights these are the RS weights.

Same with fuel capacities:

fuel: 92 l / 20.2 gal

Hey Bill:

Could you fax me the documentation once you receive it from Kary? The # is (202) 383-2114. I would like this info for my file. I have a hard time believing the CS weight was that light, but would be delighted to have it confirmed. Maybe a Christophorus article from '95 would be more accurate than the various magazine road tests, which I find very unreliable.

There were a lot of small mechanical differences between the RS the Cup and the regular car--I think Hank Cohn would be the best source on these changes. Hank?...

I'm cleaning that 3.8 motor up for you, Bill-- you can eat off this thing...

Dbltime

Lee,

There were 5 3.8's racing CMP. 2 RS cars and 3 Cup cars. After 23 laps 1 RS and 1 cup car finished ahead of me. It kills me spend a skillion $ for something that is not broken. You should be paying me for this killer STOCK 3.6 Get serious on that price before I pull the trigger on another motor that I found.

Definitive document is "Service Information Technik for 911 Carrera RS", Porsche p/n WKD 499 620.

Kary hit on the main points.

Remember the Club sport (option M003) was a legal road car unlike the Cup. As a result it was delivered with both wipers and "thin glass quarter windows". Only the Cup has plastic side quarter windows. M003 and Cup did share the identical "tub".

You can buy it from Gert at Carnewal, from memory about $30.

Bill, just finished reading your experience over on the racing board. Sorry to hear you can't be under horsepowered and compete ;-) It does sound strange but I guess I can understand how it could get out of hand rather quickly.

Let me (us) know how it goes.

As I have said all along and I have 100% proof........993 RS CLUBSPORT ROW cars were available & ordered with all kinds of optional equipemnt from Porsche AG. The Porsche factory built many 993RS and 993 RS Clubsport cars with full carpeted/leather interiors and WITHOUT any type of rollcages and /or roll bars. The fact is that over 80% of 993RS factory cars had complete AIR CONDITIONING packages, Sunroofs with POWERWINDOWS and radios and even leather seats that tilted forward.

I have seen 3 993RS Clubsport cars and they all had creature comforts. Dont ASSUME that you have to completely change (cut the roof OFF a $9,000 fiasco) or GUT your 993 to make it a 993RS.........you're wasting time and your money. Nothing was absolute in the build of these cars as you could order anything from your local ROW dealer's standard option book.

Lastly, Porsche AG has done the same thing to USA customers for years. When a COOL racetype but STREETLEGAL model debuts...........964RS, 993RS, 993GT2, 996 GT3..........Porsche states that these cars have too many specialized parts and specific non DOT or EPA equipment and would be impossible for them to import and resell. Basically their hands are tied---I call this bogus reason#1

BOGUS reason #2....is that these cars ARE VERY STRIPPED AND IMPOSSIBLE TO DRIVE ON THE STREET -- SO YOU (the US consumer) WOULDNT WANT ONE.

Dont get me wrong I love Porsche AG and their cars but they have been saying that for years. Only just recently did their chairman state after the GT3 wasnt available in the USA...........that all models would be availble stateside. Thereafter we received the 2002 GT2 and 2004 GT3. It would be nice to get a GT3 RS streetcar with A/C, powerwindows and CD changer and no cage. $100 states that Porsche is building GT3 RS streetcars with the good stuff!

Good point - well made, on the variations in spec...
my own car has a/c,airbags & power windows..thankfully it has the recaro buckets,no sunroof and all of the finer points of RS cars. I feel these additions can help you enjoy them as road cars.

Unfortunately I'm not home to send you a copy of the RS/RSCS book. I would like to make a comment though regarding the weight question. I was reading the Porsche Club of Australia competition rule book and it lists the RSCS weight at 2690! What is even more interesting is that they class the RS Touring on a separate category with weight of 2910! Finally to the comment i have been making since day 1 about the Normal D stock 993's is that the same organization lists the 993 C2 with weight of 3020 which is 40 pounds less than PCA listing and makes more sence since I have had a very hard time bringing with additional weights my 993 to 3060.

Danny:

My track car has the mufflers missing, Fikse wheels w/ Hoosiers, Momo seats and a fiberglass nose. All AC etc is still in place. It even has the sunroof. I have a full cage with all interior pieces in place. With a full windshield washer reservoir, 1/2 tank of gas and 60lbs of ballast, the car weighed 3041. There is now way these thing ever weighed 3060 unless the factory filled the tires with antifreeze.

Don't protest too much though because lighter weight will cause our weight to HP ratio to increase thereby negating my hard work in trying to get bumped down a class where I can be semi-competitive.
