Rear coilovers on supers

[Simon]

Sorry, my post was inclomplete again, I ment single shear on the trailing arm, since the upper mount can be made into a double shear mount.
Anway, thanks for your answer!

Why does the bolt in the alloy arms work in cantilever (and why doesn't it with the stock arms?)
Is the damper under a different angle compared to the stock arm?

And only the topmount is of concern, since it's the one that gets a bending load?
