Compression and Rebound Valving

[xtremezae]

All suspension Gurus,

Question on Compression and Rebound Valving numbers.
What does the number represent?

Example shocks that have;

3.0 rebound, 3.0 compression valving
or
4.0 rebound, 2.0 compression valving
or others

What valving suitable for street/road use? track use? and combination of road and track?

Thanks,

Please tell me you aren't referring to the numbers you see in driving games like Forza and Gran Turismo.....

These are Bilstein numbers ....
BTW, I dont play games ....

Just checking. If they only list adjustments in whole numbers, and your adjuster "clicked" each time you turned it, you can assume those numbers refer to the "click" adjustment, but the manual would need to tell you where to begin counting your turns from (clockwise or counterclockwise for example). But since it looks like they give you a fraction then it's possible it just refers to number of turns of the adjuster 3.0 turns, 4.0 turns, 1.5 turns, etc. If your shocks have clicks it'd be easy to figure out which it is.

I wouldn't say they are forces in compression and rebound because those forces are usually represented as force/displacement or force/velocity.

Thanks noob4life....

Forgot to mentioned, these are non-adjustable Bilstein with fixed valving. Did some searching and found some info.

You are correct, The numbers represent damping forces measured in Newtons at velocity of 0.52 meter/sec. the number is in 1/10th.

The higher the numbers, the higher "firmer" damping forces. Now, the question is what kind of damping forces is good for street/road, track and road&track.

Wondering if any of the EVO members would have some experience or recommended setup for front/rear. My first guess is to having higer rebound than compression. But at which levels/numbers ?

It will probably have to depend on your spring rates too.. but a good starting guide is to make the rebound 50-75% higher than the compression..

It also makes for a very comfortable ride too

BTW, do you know what is the rebound/compression specification for 8MR/9MR Bilsteins ?

Thanks,
