Here is a shot of the right rear suspension. Notice the hollowed out rear upright. That is to allow air to flow through the upright to more effectively cool the brakes. That is a trick we took from F1.

Interestingly, you can also notice 2 "false start" rear upper control arms laying there on the table. One of them is the fault of a customer of ours who came in one day with his new Ferrari 430. We begged him to put it on the lift and when we did...well, we saw a better way. The other is the fault of Cosmos (Finite Element Analysis)...telling us we needed more material.

Also, notice we carefully lined the push rod up on the rocker and shock to minimize any side loading that could occur. Finally, you can also see the lower push rod is also mounted in double shear. That way we can get away with very small bolts and fasteners and make a very strong part.

From this view you can see the rear bulk head is slanted backwards--just like an original car. It made the actual manufacture of the part extremely difficult. There were almost constant battles between engineering and manufacturing on this--engineering always won--and I lost my hair (but unfortunately, not my waist!)
