Polyurethane Rear Upper "Banana" Link Bushings

These findings are consistent with the internal limits of the system.
This is the rear bearing carrier, and the bolt that holds the upper link and conical washers in place.
Note the size of the hole provided by Porsche. No matter how much compliance the conical bushings provide, when the bolt hits the sides of the hole - further motion is stopped.
These pictures show how much range Porsche designed in to their system at max, and is consistent with our range measurements also.

When system is set up correctly that upper arm bolt will not move at all. Concave pieces on both sides keep it centered and rubber in bushing flexes as much as is needed. Bolt and concave things are not meant to move at all once car is on the road and suspension is in normal driving position. If there were any movement in any other part than rubber entire setup would be build differently. Do not leave concave spacers off.
