When I got the chair, it was mounted on the body with only 1/4" rubber pieces.
As I installed a bigger tire on the sidecar, I had to lift it from the frame.
I bought 7 hockey pucks for $8, drilled them and installed them as a vibration damper between the fiberglass and the frame.
According to a passenger that I took for a ride today, none of the k100 vibrations can be felt in the sidecar.
I believe that the density is perfect and it makes a huge difference on the riding's comfort.
The price was right.

I used Toyota Corolla engine mounts on mine. Works a treat. Bella says they are very good for isolating the vibrations and appreciates it tremendously. Well, I am pretty sure that's what she says. Strangely, a lot of her comments sound very similar.
Woof.

Does Bella reacts this way when riding?
From what I learned about the Aussie language, I believe that she says: "stop for a cold one".

No...thank god!

great to see you out and about bert .....at last
