Damper rates

How do you measure damper rates?

Springs are easy KG/ MM or Pounds /Inch

Where do manufactures display them

The damper rate is measured from the Force/Velocity plot on a damper dyno and is the gradient of the line.

 

A damper will normally have more than one damping rate; low piston speed and high piston speed damping rates & these will be different in bump & rebound as well. A damper with one rate in bump and another rate in rebound is called linear and one with two rates is 'hopefully' digressively valved.

 

The low speed piston rate is usually higher than the high speed piston rate.

 

A bit more about it here:

Unless your dampers are supplied with force velocity plots from a damper dyno you will have to get them tested to work out their damping rates.

Just opened the box of dampers from you Blink. Is that what all those graphs are?

That is correct Terry, however when the dampers are 'matched' it is a force/displacement graph we use rather than the force/velocity graph. - if you bring them with you when you visit I will sit down with you and go through them.  :t-up:

 

We do feel it is important to provide the Dyno Plots from the dampers we sell, as like a chassis dyno plot, once you learn to read them they do contain lots of useful info.

P.S. When we do get chance to update our website we will have an area dedicated to damper dyno plots from various makes/types of Damper with an explanation of what the graphs show.

That might be to much information but thanks for the offer. Just need blingy shiney new things to put on car, make me feel good lol.
