Just fell across this thread. Since I lived in Lakewood, Colorado, for years and drove a '70 911E in the same red color, it's very interesting to me. I knew Storz Garage founders Bill Randle and Al Lager, both gone now, and my car(s) graced their shop a few times. In fact, they named their shop for a 1950s Porsche factory mechanic, and Larry Braun created a sculpture of him working on a four-cam engine. Larry owned the Gloeckler-Porsche that had somehow found its way to Denver, and I helped him trace its history. The car is now owned by Herb Wysard in Fullerton, California. But I digress.
I got my E in 1973 and drove it home from Kentucky with collapsed hydropneumatic struts, so the first job for me was changing to torsion bars. I autocrossed and time trialed it heavily, then in 1992 ran it in PCA's first club race, at Second Creek, near Denver. It was our daily driver and went to several Parades. I put well over 100,000 miles on with no engine work. Stupidly, I sold it in 2002 to help pay for house remodeling, but the new, younger, owner learned track driving in it at Mid-Ohio. He sold it to a guy in California, and we lost track of it. Here's my late wife driving it at Aspen in about 1974, before I Hoovered off those ugly side stripes.
Of course, it originally had 14" alloys, but the steel wheels had a set of bald Michelin XWXs for track use, as that was the trick set-up in 1974. Torsion bars were 22s and 27s, I recall. Did most of the work myself, including lowering it, with advice from the late Grady Clay, who became a friend. Today I still have the '65 912 that I bought in 1968, but that's another story. I loved the E because it had bottom-end torque and could beat an S out of slow corners and in autocrosses. The MFI made the engine so smooth and responsive. Even today I would pick an E over an S any day of the week. OP, if you get to any Rocky Mountain Region events, keep your eye out for a geezer driving a lowered white 912.
