Rear shock perch change required for PSS-9?
This information was posted on another topic:
Car looks great. For what it is worth, you made no comment about upper shock mounts (perches) for the rear shocks being changed. We found that as the PSS-9 is designed around a motorsports application vs simply a street car modification, we have had to change the rear shock upper mounts (perches) as there is a difference in the seat design of the PSS-9 vs stock shock.
The stock shock and upper mount have a taper where the top of the PSS-9 is more flat. What you have is the PSS-9 upper mount only contacting on the outer edge of the car mount due to the taper on the factory car mount. We change to a monoball set-up that matches the PSS-9 upper mount.
I spoke to Bilstein about this prolem when they first came out and after some research, they confirmed the differences. They are now recommending that the rear upper mount (perch) be changed as part of the installation of the PSS-9.

Is anyone else aware of this issue? What are the pros/cons of changing the rear upper shock mounts to monoballs? Approx. how much?
