Q & A
Gary, The ERA manual states the bolts for the rear trailing arms should be at 45 degrees and angled towards the front pivot (not symmetrical). My suspension guru, who was drafted by Corvette Racing for causing their LeMans wins, tells me they should be closer to 30 degrees for optimal alignment. Are your suspension pickup points at the upright symmetrical on the CAV?

Not exactly sure what you mean by symmetrical in this case, but my can is a mirror image from one side to the other. The angle of those bolts should not effect suspension geometry. Assuming your clevises are centered about the large stud going rearward, rotating the bolts inward at the top, for example, will rotate about the ceter of the ball and should not change the geometry. I could be wrong as I have not seen your car in person.
On the CAV rotating the bolts will definately not effect the suspension geometry; however, if they are not fairly close to vertical you could get binding of the rod ends at full suspension bump or droop. It is fairly easy to check on jacck stands as you can remove the shock and spring and run the suspenion up and down by hand and look/feel for binding.
