Looks promising. The fact that they made a shock dyno to actually test the design says a lot. And the color coded shims are sweet!

Maybe we could start bugging them to step it up for the 1/8 scale buggys and truggys!

I've always wondered why this didn't exist in RC and how long it'd take for someone to make it - pretty cool.

For those asking why it's implemented in the way it is, I'll explain briefly:

In the rebound direction, the shaft speed is always physically limited by the spring rate and preload - the shaft can never return faster than the spring can rebound. Thus, the shaft speed can never get very high. Because of this, a ported damper is usually sufficient, or at least can be tuned to work *fairly* well with ease. As a sidenote, in this particular application, having shimmed damping in both directions would also require a much more complex piston - probably why it's not there.

In the compression direction, things are very different. The shaft speeds, while not completely unlimited, can reach much higher rates - because you are only limited by how fast you can hit bumps, and square edged hits can result in quite high shaft speeds. At these shaft speeds, the port area (which on a conventional RC shock is the same as what is available in the rebound direction) is going to be overwhelmed and thus damping spikes will occur.

The benefit of shimmed compression is that as you hit bumps and shaft speeds increase, more flow area can open up, to stop the damping curve rising progressively and causing spikes. It also means that you can run more low-speed compression damping (i.e. a smaller initial port area - which in this particular implementation is also your rebound damping port area) - which is useful for support under cornering loads and jump takeoffs / landings - without sacrificing performance in the bumps / rough sections like you would do if you didn't have that extra port area that opened at higher shaft speeds.
