Ultimate ST thread

[Mark Morrissey]

Thanks Michael. I knew I could count on you. I agree and felt the language of the article to be generic... There was no 400mm Momo, aside from that big Monza wheel I had. But, that wasn't a true Momo. Could they be referring to a standard wheel as a standard competition Momo of the time which would 350mm for the most part?

Sorry Raj to have turned another nice car thread into one of the steering wheel variety. Okay, I'm stopping now

Well, keeping it within the ST frame of reference, No. I think they are referring to the Porsche Factory Sport 380mm wheel (thick grip 914-6 and RS). The MOMO would have been an even lighter 380mm alternative even with the addition of the MOMO hub, though as you say the 370mm and 350mm were more common.

Do you mean the 2.4S Michael Keyser bought in 1972 to travel across Europe? Both, this and the 2,5 S were painted identical.

Does anybody know the lock-up ratio of the LSDs fitted to the STs? Was it stock or higher? I believe the lockup ratio at the time for a stock 911 fitted with the ZF LSD was 40%.

[Chuck Miller]

The usual factory settings were 40% stock, and 80% performance... I would assume the ST's were 80%

Hope this helps,
Chuck

Anyone recognize these STs? One is using the late 72 front oil cooler mod, and running 9x15 Fuchs in the front with wide rear flares (look like RSR flares) with probably 10x15 BBS wheels. Maybe the pic was taken in 73 with the car modified with RSR pieces. The second pic also shows an ST with wider rear flares, but running in rally competition with narrower rear wheels.

Top photo is Claude Haldi at 1972 Euro GT Estoril (no. 62), next to him inthe same photo is 'Gedehem' (both cars prepared prior, & serviced there by Garage Haberthur).

Lower photo is Heinz-Walter Schewe in a 1973 F series Carrera RS 2.7 , at the 1977 Rally Costa Brava (Spain). This car was fairly heavily damaged on the drivers side rear previously at the 1976 RAC Rally (or at least a Carrera , driven by Schewe , wearing these plates).

Thanks for the info, peekaboo, I found the Haldi car (orange/white) in that famous Christophorus cover pic barely peeking out from behind the car on the left, and then again at the Targa Florio. It is interesting that the second car, the 2.7 RS, would have RSR body work when it was being used for rally competition. Do you know if it were being used in circuit competition at any time. Maybe the body work was done after the 76 crash you mention. I don't think I can see a ducktail on it, but maybe just not visible.

I have not seen any 911's that H.-W. Schewe drove prior to 1974. But for 1975 thru 1977 he seems to have had at least 2 cars . And they were also seemingly always widebody flaired (1974 too , but I only have one photo of him in 74) . Except for possibly this 1976 RAC event - but I don't know. So even though it is very hard to tell in the photo I have of this car at 1976 RAC. My quess is that they are there (and yes the car in that 1977 Costa Brava photo has a ducktail , you can see an edge peeking out just behind the left rear qtr. window).

Believe it or not , He ran a RS / RSR 3.0 group 4 wing with wide flairs on one longhood at the 1974 Nordland Rally . I do not know if he ran that wing for ALL of 1974. In all other photos I have of him in an longhood, which are all from 1975-77 - his cars have ducktails with the wide flairs. In 1978 he seems to have started using a short hood / impact bumper 911.

Even though Schewe ran some track (a small amount I believe) during this time period. The flairs are not necessarily for that. During rallyes , many times at the same event. There are stages that are loose surfaces and ones that are mostly paved road. So the wide body has the advantage of fitting wider rubber. MOST times during the mid 70's at rallyes , wide flaired 911's like this were entered group 4 . While the normal Carrera body 911's were entered group 3. But STRANGELY , on occasion I have also seen wide flaired 911's entered group 3. The times I see this , the events are always in France. I have never been able to figure this out. Schewe always had his porsches from 1974-77 , entered in group 4 at rallyes.

Here's a photo which I am now thinking actually was another car (and there was plate switching)... at 1976 RAC . The reason I think it is another car. Is that I have photos of him in 1974 - 75 , in a Carrera flaired & painted just like in the 1977 Costa Brava photo above.

Again , the flairs below are hard to see from the damage. Remember even though the front are not as damaged as the rear , and look normal width. When cars are white and viewed from the side , many times wide flairs in front look like they are not there. So I really do not know. :

Raj:

I had noticed that feature too on many STs, and my conclusion was that most of the cars with the early style ST bumpers were being used in rally (like the Monte STs) events where the aero effects would not have been as much of an issue. I did find one pic of the 71 tdF (I think) where the later 72 style bumper was used, but most of the pics showing STs on track events (granted most were in 72, not late 71) the cars had the air dam type bumper. All of the Safari STs had the early style bumper, maybe another reason was front ground clearance.
