I expect that the Ferraris were lighter and got better gas milage.

I actually have three of the 250GTs (five if you include the Drogo cars)


As for ride height, I think you might be remembering this picture






And I also adjusted ride height on this one as well as changing the tires




The third is a model of the 1st in GT and 3rd over all at Le Mans in 1961



You have a better memory than I do!
