For those who like the TEIN EDFC
 

The TEIN EDFC on-board damping controller box sits on top of the strut tower, so in order to use this system the strut tower brace bar has to go.

So I prefer to adjust the damping with the car stopped than to remove the strut tower brace.

The stut bar can stay, the stepper motor is very small. Look for Skiddazle's pics of his engine bay....

Where is this "you have to remove the front bar" stuff coming from? I've heard it now from a couple of people, but there are several people here with the systems and the bars still in place, so it obviously isn't true.
