Anthony,
Making the original type suspension is extremely difficult and time consuming to do correctly. Frankly, I would much rather prefer no one ever ordered an original one again—even at the current pricing. They are just that difficult to do. But, even so, we are currently making billet copies of the original calipers for those guys who just can't live without them and want to get away from castings. I can’t blame them.
It would not surprise me if the newest Shelby cars came with billet suspensions. I remember several months ago an engineer from HST was here in our shop showing us drawings of OUR suspension they had just reverse engineered...
He told me they copied the suspension off of Turk’s car. He expected me to be shocked while looking at the drawings. I just smiled and told him, "That suspension is about 6 generations old right now." (Currently, that suspension is about 10 generations old.)
