Hiya folks,

There is another type of shaft volume compensation which was evident in vintage rc cars of the 70s to early 90s.

Foam compensation!

a blob of foam was placed under the piston and as the shock shaft extended into the damper body, the foam compressed.

This prolly didn't work as well for large or long shocks as the amount of foam will have to be quite extensive...

I believe yokomo, ayk and some other companies had this kind of shocks in their old vintage cars.
