It sounds like everything got slowed down but not really sure?
The base valve meaning the needle valve? Low speed?
I was hoping for a larger piston diameter opening for the high speed valveing
Do you have a dyno yet? That would really help

shock dyno would be really helpful.

Evasive Spec includes both Small Base Valve and related Smaller Diameter Shims.
- In both base vales (normal and small) there is a bypass. This bypass controls oil flow at low speed damping. (Slow Speed Damping is most related to initial steering response). The bypass valve on the Small Base Valve Spec is smaller, therefore it is better able to control the oil flow, and the damping force is greater at slow piston speed than a normal base valve spec. coilover. This results in improved initial steering response, which can easily be felt on turn-in.
- The Smaller Shims allow for quicker Damping Force (DF) response due to diameter of shim. The faster DF response means quicker steering response, quicker transition from compression to rebound and vice versa, and allows the damper to react more quickly to any type of movement.
- Smaller Shims have a greater range of motion in terms of bending. This allows for more oil control at low speed damping. The larger shims have more of an on/off type movement at low speed damping.

So far I like the fact that the bypass (low speed) passes less fluid than what the normal one did.

Great! 
Do you know how easy is to change settings on the KW Clubsports? I know it's a bit off topic.

Rebound is easy to adjust, while compression requires you laying under the rear of the car (and under the front with the front jacked up - and it's much more difficult sticking the needle adjuster into the pin and make a change compared to the Tein's knob that can be adjusted by your fingers alone.

The KW Clubsports and V3s dampers are the same. Rebound is adjusted on top of the shock in the engine bay and trunk via an allen wrench, while the Compression is adjusted by a small 90-degree opening (window) at the bottom of the shock.

a more in depth description of the shocks..
The Super Racing (SRC) kit is developed by TEIN to be used on the street and track in any country. The concept behind the coilovers is to produce a coilover that could be used to drive to the circuit, compete, and drive home. The vehicles we use during development of SRC range from lightly to moderately tuned. Some of the key aspects during development of the SRC are performance, drivability, and comfort. The Evasive spec S2000 SRC kit retains many of the same fundamentals but places a greater emphasis on track performance.

But I thought the shims on a damper control the oil flow at high-speed damping.
What exactly do you control with the 2 dialing knobs on the dampers?
I know top is rebound and bottom is compression. But is it high-speed or low-speed?
Is it the opening size of the base valve you have control over with the knobs, or the bypass in that base valve or even something different?
Thanks!

the knobs adjust low speed.
technical:
the adjustment knobs affect high speed overall flow but is used for low speed adjustment. The more you decrease low speed oil flow by the knob, the highspeed oil flow will be decreased by roughly that same amount.
There is a mixture point between low speed and the shimstack (highspeed). It all depends on where the designer/engineer thinks the crossover should be. On the regular SRC's it's really hard to get proper low speed control without making highspeed kidney pounding. Usually cheap shocks have a highspeed that will flow tons of oil to prevent the seals from blowing. Not the case with the SRC's, they did the exact opposite.
I wish they would just post a dyno chart. It would make spending money much easier
To the OP, I think asked this question already but did not see an answer.
is the new shimstack capable of passing more fluid at full flow in comparison to the regular SRC's
