This is just a fantastic thread, and just amazing pics, many I've not seen before. Also, great discussion on the dynamics as well.
Fabrizio's Super pic is really something. Compare this to period TI Super pics, and the TI Super is leaning just as much, but the front wheel is still on the ground, tons more suspension travel. Nowadays they're fastened up tight.
It's amazing how much lean is involved with the old GTA's and GTAm's. I know the roll axis, the axis that connects the front and rear roll centers is pretty odd with the Alfas, which contributes to it. I'm wondering how much the sliding block had to do with it. They may have had to keep it extra soft in the back to make it work well.
Not that many GTA's had aluminum floorboards, which the books say they abandoned due to lack of structual integrity, or until roll cages got better with the advent of the GTA Jr. However, many pics of period GTA's were cars sold to Autodelta, which were early cars, which may have had the aluminum floorboards. Adriansen's book states that most the alum. floored cars were under serial number 100, with number ranging from 1 to 999. So really, only a handful of GTA's had them. My car may have had them, but certainly doesn't now. My car was first owned by the son of an Alfa Romeo dealership owner, in Siena, IT. He said he put every Autodelta piece he could on there, and I've got a few pics of my car back in the day, none on 3 wheels however, but definitely one of it massively understeering around a corner!
My own car has just a front 26mm bar, no rear for now. It's an understeerer at present, and doesn't lift its front wheel. I have a standard trunion bar, too. My car weighs 1870lbs w/o gas, which isn't ultralight at all. I'm racing against another '65 Sprint GT weighing only 100lbs more than me!
