928cs

I disagree, to my knowledge, my car is the only one with electric seats.
The regular seats are manual only, with no height adjustment.

For the moment, I have identified, either by pictures from articles or by VIN:
- Three 1987 MY prototypes (One red, two white)
- Ten 1988 MY Euro production models
- Two 1988 MY US production models
- Four 1989 MY Euro production models.
I still miss three 1989 MY Euro models and two 1987 prototypes.

My web site is down for the moment but I will try to find the time to rebuild it (when my home computer will be in working condition too...all my data are stored in it).

An SE must be lightly modified to become a "RHD CS". If you modify it, be sure you can go back to the original condition...

Samuel, do you have pics of those seats? Are they exact same as CS proto seats? I was under impression all production models have two round buttons with up/down adjustment for front and rear end of seat bottom.

I will show pictures as soon as my computer will be OK

I have even sat in two different CSs with these seats, except they were full leather, the last Euro 88 and the last 89 (now destroyed).

CS also had Sport Shocks (red Boge's) and CS springs, and I presume most if not all were ordered with the rear differential.

I'm looking at ways to reduce the weight of the SE as I'm competing against a 996 GT3 RS and he's got a considerable wieght advantage.

I also tried to adjust the dampers and the adjusting **** has seized as I've never adjusted them in 7 years.

standard dampers were not ajustable.

Adrian C. may have informations on the SE engaged by AFN in 1988, in a racing serie. It was raced by Tony Dron. This was a white car.

I would avoid to modify too much an SE if I were you.

Now that my home computer is fully operationnal again, I will try to show the list of mods of a CS versus a regular S4.

Here is 1988 factory car (either wp0zzz92zJs845061 or wp0zzz92zJs845064).

Thanks Samuel. I had seen this pic in your website before but was under impression those seats were used only in factory protos and/or demos and not in production cars sold to customers.

There is a very good article on the 928 CS in the October 2007 911 & Porsche World (UK) magazine page 54 - 60, titled "A Lighter Shade of Porsche".

Basically the author of the article stated that the CS was as follows:
Externally, there was very little to differentiate it from standard models. but a closer look does reveal some differences. No rear wiper. no sunroof. no rubbing-strips along the car's flanks, wider (similar to Design 90) wheels and tyres. a dual exhaust pipe and a CS sticker applied to the near-side front wing (LHS). But underneath the still futuristic - looking body work the differences were quite extensive.

The engine is based on the Euro S4 manual unit (coded M28/41), but pistons and con-rods were balanced. It had special camshafts, a specific DME, a lightened exhaust, and lightened alternator and air conditioning compressor. All CS engines were stamped with the two letters 'SP' after the serial number, to set them apart from standard motors.

The transmission is the same as the manual S4, except that the gear-shift lever is 20mm shorter. There's one less torque tube bearing, no torque tube vibration damperner and a smaller differential ratio. Suspension is based on the S4, with the differences being Sport Shock absorbers (avaialable as optional equipment on the standard S4), shorter and stiffer front springs, and a widened rear track with 17mm wheel spacers. Club Sports also had a smaller, lighter battery, a smaller tool kit, no central locking and a simplified wiring harness - enabling items such as the stereo were also missing.

That's quite and extensive weight programme.

The SE was basically a CS that had all the luxuary items fitted back on. It had the sound and feel of a sportier 928, but wasn't anywhere near as hard core.

It is reckoned tha just 19 CS were built between 1988 and 89, with most remaining in Germany, a couple for the US, four for France and one sold in Austria.

In the early 1990s, Porsche was planning to run 928 Club Sports in a Cup race series in Europe and as part of this, it developed the 928 for motorsport use and made a number of special components, including uprated anti-roll bars, shock absorbers and brakes.

This is the main gist of the article relating to the 928 CS.

You mean like this? No, it's not a CS, it's my stripped-out racecar and could be called a CS-type 928:

I have to order this 911 & Porscheworld issue. Thanks for the extract of the article. Is there a real CS in picture in it?

For your information, the first 1989 CS production car was used by Porsche to test solutions for the 928 GT Cup.
This car is now in France since September and belongs to a friend of mine.
It has been really modified during the years and is not street legal anymore.

Regarding the sticker, it was possible to order a car without it.
Nice car SwayBar, is it an S4 or GT?

IIRR car in article is UK S4, SE or GT which was modified to closer to CS spec. Article is comparison between 928 and 968 CS.

Thank you Erkka.

I need to repaint my car. Does someone know where I can find an original grey CS sticker?
Thanks in advance.

I would try http://www.mittelmotor.de. They list 928.559.339.01 silver sticker for 95.82 euros. Black version is not listed.

http://www.928gt.com lists both black 92855933900 and silver 92855933901 but asks close to $300 for each.

If that doesn't work out some add companies can probably make copies of your original sticker if its still good enough condition. They can make new ones out from precise photos and take into account fender curvature etc.
