What's Special About This 550?

[cegerer]

Everybody's seen this car, I'm sure. But it featured something for the very first time on a racecar. Something that is found on nearly every race car today, including drag racers, NASCAR, motorcycles, you name it. Any guesses? -- Curt

Mark, I would hate to be "seat-belted" to a motorcycle

[MarkP]

Uh, yeah, you haven't heard about those?

Well if it was a 550 # 5 with a hump I'd guess it was Porsches first use of a wind tunnel to improve arrow aerodynamics.
But that is 550 # 3 0r 4 before the hump. So I'll keep digging
But a Sponser other than Porsche is a guess

well it says radio on the front so maybe it's got in car radio into the pits?

Disk brakes were used on race cars as far back as the 30's...

Rear view mirror?

[Paul Franssen]

I'd vote for advertising or sponsoring...?... Disk brakes? I thought it was Jaguar/Lockheed first, in the fifties??

Advertising is correct.
That shot is included in a "Monterey" screen saver I sometimes use.
Always happy to share that bit of history with anyone that sees it.
