I just re-used the ones that were on my 150K mile car when I rebuilt the suspension.

Thing is I'm also changing the springs, so I'm not sure how the new springs would fit into the groves created by the old springs, plus the cost for new ones is only $26.16 for all four corners.

Suggestion
On the oem springs, there is a colored dot that tells you which size to use, maybe for some sort of balancing or compensating (ha ha) for an imbalance in the springs, like a minor adjustment for corner weighting.

Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Hello,
I'm getting ready to put my Koni FSD struts and shocks onto my 03 Boxster S. I am using springs that will lower the car 1" at all corners. The one thing I'm not sure about is the Compensating Plate size I need to use.
In this picture of the front struts part #5 it shows two different sizes. It shows 3,0 Mm and 6,5 Mm and I have no clue which size I need. Also the chart has an X out to the side, so is this an optional piece?
In this picture of the rear shock part #3 it shows two different sizes. It shows 3,0 Mm and 6,0 mm and I have no clue which size I need. Also the chart has an X out to the side, so is this an optional piece?
Appreciate any help on this!
Just watched a video of the shock being taken apart and put back together and the Compensating Plate is needed as it is what the spring sets into. I'm going to go with the 3,0 Mm size unless someone says different.
On the oem springs, there is a colored dot that tells you which size to use, maybe for some sort of balancing or compensating (ha ha) for an imbalance in the springs, like a minor adjustment for corner weighting. I've only ever seen the smaller ones in use.
Hope you like the FSD, i loved mine!
I don't know why that site calls them compensation plates. They are rubber and the springs sets into them.

Most people reuse them, but I want new parts as my car has 127k miles on it.
I've had the KONI FSD struts, shocks and lowering springs for over a year and just have not got around to installing them. I've read your post on them and others, they seem to be great.
I just re-used the ones that were on my 150K mile car when I rebuilt the suspension. Everything seems to be just fine.
The 3 mm thickness translates to .118 inches of ride height, for most of us, it's not a big deal.
That's good to know. Thing is I'm also changing the springs, so I'm not sure how the new springs would fit into the groves created by the old springs, plus the cost for new ones is only $26.16 for all four corners. I also decided to go with the thicker pieces.
I suppose this would be why it takes time for the ride height to settle in as the springs will be making new groves in the rubber.
New Front
New Rear
What luck! I'm just about to redo my suspension and am wondering which compensating plates to order.
I asked a well-known UK Porsche parts dealer about this, and their reply:
I'll be going with the thicker ones for my KONI Special Active + Eibach springs.
I took the back wheel off and looked at the piece, on my car it's definitely the 6,0 mm piece. After looking at a picture of the front 3,0 Mm size piece, I felt it was too thin and decided to go with the ticker one.
This is the 3,0 Mm compared to the 6,5 Mm for the front.
This is a source reference. Confirm exact model applicability in the original material.
