What about these Spyders? Special Editions?

Postby &1 » Thu Nov 22, 2012 5:54 am

Ever seen this rear? What Spyder is/was this? What about this extra oval grill on the rear?

And what about this front screen? It's a pretty high screen (split) and I've never seen it on a Spyder. Does this Spyder have 2 spare tires? (one under the bonnet and one on top)

And this fighter airplane like glass bubble?

Ever seen a/the spare tire on this spot?

There were many prototype modifications like May's wing he fitted on his 550-0031 and tried to race it at the Nürburgring 1000 in 1956. He was challenged by the Porsche Werks team manager and was disqualified from entering because he whipped all their factory cars in qualifying!

Many drivers had cooling issues, so the 550 with the additional grill which raced at Sebring allowed better airflow through the engine bay. This is why the later 550A had the grills a lot further down the back of the rear deck lid.

The high split screen is on 550-0051, when it was set up for rally racing. Spyders were quite successful in rallying as they were endurance cars with a good power to weight ratio. The screen was usually from a 356 split, and they did carry 2 tires - one under and one over.

The bubble canopy was only used at Hockenheim in 1955. It was supposedly for aerodynamics, but Friedrich-Victor Rolff nearly passed out from dehydration because it was so claustrophobic in there - he finished 6th out of 8. Spyders took out the first 6 positions.

The spare was positioned in the passenger seat because in races like LeMans, drivers had to have a passenger seat (many used a lightweight rattan one) a full tool kit for repairs and also a spare wheel to enter. For better balance in the car they put it on the passenger side to counter the driver. In most races the spare was removed from the rear to reduce weight.

hope this helps ;)

The wing was interesting. It is the first known use of this huge aerodynamic benefit (though disqualified for all the wrong reasons). Chapparal later made effective use of the wing and was also banned.
