MXSCandinavia went on in the thread to demonstrate the shim stack modifications needed to gain separate control of high and low speed damping:
- Preloading a soft shim stack increases damping force at low speed and softens damping force at high speed
- A crossover does the opposite with softer low speed and stiffer high speed
- A soft tapered shim stack matches the crossover stack at low speed and drops off at high speed
MXSCandinavia went on in the thread to demonstrate the shim stack modifications needed to gain separate control of high and low speed damping.
Tuning to get the desired damping force curve shape is simply done by hacking: adding or removing shim stack preload and crossovers to get the desired damping force curve shape and hacking around on stiffness to get the desired damping force value.
The numerical test bed of Shim ReStackor makes that simple, easy and intuitive.
