Porsche involvement with Le Mans started in 1951, but an outright win eluded them until 1970, with the type 917.
In the meantime, however, in the small capacity classes, and the Index de Performance, they were always a force to be reckoned with.
Of all that twenty year span, 1958 was without doubt the highlight. 5 cars entered, 4 finished, in 3rd,4th, 5th and 10th places.
Opinions of the RSK pilots varied dramatically as to the efficacy of the "Mickey Mouse Ear" fins. Some drivers would refuse to get into an RSK if they were fitted, and just as many would refuse to get in if they were not !
Our subject, the 4th placed car of Barth/Frere did have them and finished strongly at 100.87 mph.
