Hello Samuel
The car featured in the article was one of Adrian Clark's cars. A car modified to be something like a CS, but was not intended to be a clone of one.....

I have seen a few of those stickers on European 928s; look OK

Thanks for the informations!
I will try the mittelmotor site first.
I have no doubt Nick's stickers are nice but till I have not seen one "in the flesh", I prefer to have a real one.
I have even sent Nick pictures of my car's sticker as a model![Wink](https://rennlist.com/forums/images/smilies/wink.gif)
To answer the first request, here are the differences I have found between a regular S4 and a CS:
- Exterior:
CS sticker on the front left wing (black for the white and grey cars, light grey for the red and black cars)
CS rims with no tyre pressure sensors for the '88 model, only the '89 have them.
Wider rear track by the use of 17mm spacers (like the '89 GT)
Dual exhaust
No rear wiper
No right mirror for certain cars
No roof antenna for the '88 model year. There's one for the '89.
No side protection
No sunroof
Windshield integrated antenna
Engine's bay:
SP stamped after the engine number
No intensive windshield washing
No fire protection at the rear of the bay
No noise protection on the engine's hood
Under the car:
G 28/55 gearbox with a 2 before the model year's letter. The 2 indicates a looking differential.
No catalytic converter for the French cars.On my car, the central part of the exhaust is from 1983…
The two intermediate silencers are smaller than on a regular S4, but same size as a GT.
Inside:
Full black
No full leather dashboard
No central looking. There's one on my car.
No radio.
No cruise-control.
No panel under the dashboard on the driver's side.
Smaller (20mm less) gear level.
S panels with Porsche cloth for the doors.
Sport seats in leather and Porsche cloth. No eletric adjustment.
Single panel between the electric window switches.
No glove box between the driver and the passenger.
No switch to open the hatch hood. On the passenger side, the part on which it should be is marked "Sch Club-Sport " into. Sch is for Schwartz.
No back sun protection for the rear passengers.
Fewer tools into the specific place (not the case for my car).
Smaller battery (50 Ah).
Specific electronic boxes for the ignition and the injection.
The part's references are 928 618 123 12 for the LH brain and 928 618 123 13 for the EZK.
Those references are for a '88 model year, they are different for a '89 (LH:928 618 123 14; EZK: 928 618 123 16 ). The EZK cuts at 6 775 RPM.
Less relays on the electric panel, of course.
Option code:
They are on the sticker of the driver manual and the same one into the boot, over the fuel tank
A CS should have at least those:
220 for looking differential
393 for wider rims (8X16 front and 9X16 rear)
474 for sports shock absorbers (Boge for the CS)
637 this one is CS reserved. The '89 GTs are 639.
I think a "regular" CS should also have 383/387 for the sport seats, but this is not the case of my car, which has electric seats.
Weigh:
My car weighs 1520 kg with all the tanks full, a "regular" one should be around 1480 Kg (official weigh for the French "services des mines")
A real prototype with no AC, under panel should be around 50 Kg less heavy.
The things you can't easily check:
Specific camshafts
Two bearings instead of three for the central transmission shaft
The front springs are stiffer than a S4.
Smaller alternator
Smaller AC compressor
General:
Of course, by using a Z-order you can get almost everything that you want…(Radio, catalyst, etc)
This is a synthesis of what I'm sure but I would like to know more…
To obtain a lighter SE, you know what to start with![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

Stenaris, I really hope your not modifying your SE in a way that isn't completely reversible. Why would you want to strip down and race such a rare model when you could get a well used S4 as a starting template and modify/gut it to your preferred specifications? Just my opinion, don't let it spoil your day.

Samuel, don't repaint your car. It will always be more valuable with its somewhat used original paintwork than with a new paint. Well, at least the last time I saw it it looked good enough for a 20 year old Porsche.

I'll agree, faded factory paint is better from monetary point of view than shiny new non factory finish.

I will decide with the man that will "restore" it if it needs a new paint or not.
I would prefer to keep the original one also but it has a lot of small defaults.
The two stickers must arrived next week.
I already have the tight cloth to restore the seats. It took 4 months to find it.
