factory Carrera CS questions

[svb]

Was the CS available in the US? What exactly did Porsche do to lighten this car and how much did it weigh? Was the engine and suspension modified? Thanks for the info....I'm very curious about this rare model.

Here is information I received from Bruce Anderson:

Tut,

In 1987 Porsche offered the Club Sport version of the 911 as (Option M-637). The Club Sport was a stripped down version of the normal 911. This model provided improved performance by virtue of reduced weight, 110 lbs. and some minor engine modifications. The weight savings came through the deletion of the rears seats, radio and radio installation kit, automatic heater control, air conditioner, sound insulation from all but the engine compartment and roof section, PVC under coating, door pocket lids, power windows, lockable front hood, cloths hooks, passenger sun visor for Rest of the World cars and other details.

The engine had hollow intake valve stems and a modified DME control unit where the standard engine cut off rev limit was set for 6840 rpm instead of only the standard 6250 rpm. The transmission was unchanged but had a short shifter. The chassis utilized sport shock absorbers, 7 and 8 x 15 inch wheels, an aluminum spare wheel and the lockable wheel nuts were deleted. The Club Sport model was offered only to the rest of the world market and only 81 were built. The price for the Club Sport was the same as the standard model with all of the extra options prompting the press to unfairly say that when you purchased this car that you got less for more. Because of the reduced undercoating the standard 10 year rust perforation warranty was reduced to two years for these Club Sport 911s.

The Club Sport version (Option M-637) was also offered in the US in 1988 and while 148 were sold to the Rest of The World market only 21 were sold in the US. The car was picked on by the press and they said that the car was less for more, because although a number of expensive options were deleted the price for the car was essentially the same as the standard fully optioned model .

The Club Sport version (Option M-637) was continued for the 1989 model year and 83 were sold for the Rest of the World market and 7 in the US and number 7 of 7 belonged to a friend of mine for its first ten years.

In general what I say about the various 911 limited editions such as the 1975 Silver anniversary model and the Weissach limited edition and the 1988 limited edition commemorating 250,000 911s being produced and the 1989 Silver anniversary model will usually sell for 10 to 20% above the market value for the standard models. In contrast there were so few of the Club Sport models that they sometimes will actually sell for even more when they change hands.

The 911 Carrera Club Sport (CS) (option M637), 340 of which were produced worldwide from August 1987 to September 1989, is a reduced weight version of the standard Carrera that, with engine and suspension modifications, was purpose built for club racing. The CS had a blueprinted engine with hollow intake valves and a higher rev limit, deletion of: all power options, sunroof (except one example), air conditioning (except two examples), radio, rear seat, undercoating, sound insulation, rear wiper, door pocket lids, fog lamps, front hood locking mechanism, engine and luggage compartment lights, lockable wheel nuts and even the rear lid "Carrera" logo, all in order to save an estimated 50 kg (110 lb) in weight. With the exception of CS's delivered to the UK, all are identifiable by the "CS Club Sport" decal on the left front fender and came in a variety of colors, some special ordered. Some U.S. CS's did not have the decal installed by the dealer; however, all CS's have a "SP" stamp on the crankcase and cylinder head. The UK CS's were all "Grand Prix White" with a red "Carrera CS" decal on each side of the car and red wheels. Although the CS was well received by the club racers, because it cost more than the stock 911 but had fewer "creature comforts", it was not well received by the public in general. Consequently, according to Porsche Club of America and Porsche Club Great Britain CS Registers, only 21 are documented as delivered to the U.S. in 1988 with 7 in 1989, one to Canada in 1988 and 53 to the United Kingdom from 1987 to 1989.

Fascinating. Nice detailed info. Anyone on this board have one? Anymore gratuitous pics of these cars would be appreciated.

I noticed the front spoiler with foglight delete. I dont imagine the red fuchs on the car pictured above were the originals...those look like 16" fuchs not 15"

TomTurtle has a really beautiful silver Club Sport, I think it's an '88.

The CS "fog light delete" option is available from Porsche today - I have it on my 84 (not a factory option at the time, but the spoiler is available as a part). Also on that pic, that car has the RUF aero mirrors and that is not stock - wheel color is not stock. Judging by the suspension and wheel lift, the suspension is not stock either.

The CS was a good idea in concept to get back to the roots of the early 911's - they just needed take it one step further with weight reduction. Charging the same price was the mistake.

It is very expensive to increase, significantly, the output of the 3.2 - a credit to the engineers.

88 Club Sport here in Denver has a gorgeous original red one.

[GrantG]

There were only 28 imported to the US. I've driven 2 of them and they are a nice drive.

[GG Allin]

I spotted this one at Road America afew years ago. It was near the Kelly Moss trailer.

[GrantG]

I think that one is fake. I think there was only one CS with sunroof and it's Tom's Silver one, afaik...

[IROC]

There's a guy here in town that has a light blue CS. I've never seen that color.

Anyone know where one can get one of those "Carrera CS" decals? I've looked for those over the years and have never found them...

[GrantG]

Dave H. has the only Gulf Blue CS and he lives in TN - must be his...

[MattKellett]

Grant - how can u tell if a fake? I notice side markers, so maybe this is a euro cs?

I'm not positive, but I've never heard of a Euro CS with sunroof.

Fenderguy's post above even indicates only one sunroof car (and I know Tom's Silver one fits the bill).

Good friend of mine has one. He imported it from Germany a few years ago. He's made more modifications than I approve of.. (big brakes, dual master cylinder, SSI, JRZ, adjustable sway bars, lot's of heim joints, racing clutch) but all mods are performance oriented and `9relatively) easy to undo.

It's a Euro so it has a few more hp than the US version as well (I think anyway). Interestingly, when we started tinkering with it the first thing we found was that the throttle wasn't opening up all the way because a hose clamp was interfering with the linkage. Made me laugh to think there was some German (actually I think it was kept in Italy most of it's life) who was driving around in his liteweight Porsche for all those years and he didn't even have full throttle.

Anyway - I logged quite a few miles in that car and it's a sharp handling and definitely feels light. That all said, my own 78 SC which I had put on an X-treme weight loss program was lighter by a few dozen kilograms, and with the carburetted and cammed 3.0 I had installed my own car was overall quicker, or at least as quick. I could out race him all day long, but he was just starting his sport driving, I've got a heavy foot and have been using it for the purposes of evil for a very long time.

The CS is a special car, and worth a premium for collectability, hence my disapproval of teh mods he's made. One could build a good replica for a fraction of the price...and as always you don't have to feel guilty for modifying it or for driving the ***** out of it.

For what it's worth, he landed it in Canada for about $40K at a time when an equivalent condition G50 Carrera was selling for $30K so he made out fine like. Here's a few photos of the car when we were wrenching it and out in the wild:

Oh geez - I forgot to mention the seats. They're the coolest I've ever seen. Standard Porsche sport seat, but upholstered in a lightweight synthetic fabric with PORSCHEPORSCHEPORSCHE weaved in. Very subtle - very comfortable - very supportive. Actually too nice to leave in the car and wear them out. Marcus replaced them with a set of track buckets. Rather uncomfortable on account of my big ass, but I agree the stock seats were maybe too nice to wear out.

Here's a pic of David Hinkle's Gulf Blue CS, the only one built in that color. Also a pic of an Irish Green CS and a GP White one...don't know who owns them.

[TomTurtle]

Hi all:
Attached is a pic of my Silver Metallic '88CS (yes, the only one Porsche made with a sunroof) and few other choice pics. AFAIK, the Grand Prix White on the pier (first one delivered to the US) and the Gulf Blue cars are both currently for sale.
As the "Advocate" for the PCA's 911CS Register, I can state that all the information provided above about the 911CS is accurate. However, nowadays its somewhat harder running the Register when the cars are purchased by anonymous collectors and "disappear".
Both the Irish Green '89CS and the '89 GP White pictured above are in that category. To date we have identified the owners/location of 18 if the 28 CS's in the US (one is in Canada). However, some of the owners do not want to "play" with us so that data may be somewhat less.
Anyone with more questions about the 911CS can email me at 911clubsport@gmail.com and anyone that thinks they have a 911CS, don't hesitate to email me and I can assist in the validation efforts.
Keep 'em flying!

[911st]

Was noted above they had 7&8/15 Fuchs but many (88-89?) seem to have 6&8/16's.

Bet some had 7/16's added to the front.

I note that the GP White car pictured has BOTH the Euro and US CS graphics and that fact plus the sunroof, indicates to me that this is a nicely done CS clone.
