I used to race a lot when I was between 25 and 35. The 88 IROCZ (left picture) I ran it a couple of times on test days, but it was too slow and tough to handle on a road track. This is the only car I have left today. I'm making it Concourse.
My good cars were 56 Porsche Speedsters (E-class in those days), a 2500cc Porsche 1914-6 and a 1960 Porsche Carrera4 (4/cam, 2000 CC's, both in SCCA class C- back then) and a B-class Lotus Super 7 w/ 2 huge Webers. This car was by far the fastest because it weighed only 900 pounds with me in it. But it was a bear to maintain. It was so fragile that I had to tighten every bolt (body, trans and engine) on the car between races, thus requiring a timely tear-down. One of my Speedsters was "acid dipped", bringing it down to 1000 lbs, but then I had to put a large piece of sheet lead under the seats to bring it back up to regulation 1265 lbs. Other than the Lotus, It actually was the fastest of all on short tracks. When I sold the car, the new owner went to the SCCA national run-offs 2 or 3 times. For those who understand this kind of stuff, in this last speedster, I modified the transmission putting a low ratio 2nd gear in place of the first gear, then staggered the other three gears, thus being able to run 4 gears when all but a couple of the competition were only running 3. If I would have kept this car (or any other other speedsters), they would be worth a major bundle today, especially the 60 Carrera Coupe which was prepared race ready new by the factory, with Plexiglas windows (except windshield), and aluminum doors and both hoods. I ran this car in both the Daytona 24 hour, and the Sebring 12 hour.
But that is all very many years in the past. Before most of you were even a glint in your father's eyes.
