    A couple of quick ones:
    1) Tractive want that controller at the mid-point between the front and rear axles. Mounting in the engine bay will not accomplish that - good decision.
    2) You might want to rotate those front dampers - the suspension is currently at full-droop, and those banjo fittings are already rather close to the central frame member. I'd rather have a bit of contact at full droop, which involves forces associated with the mass of the suspension/wheel components. As currently positioned, if contact is made under full *bump*, the forces will be much higher, and effectively bottom the suspension on the loaded corner. That will cause infinite spring rate, overload the loaded tire, and result in an immediate under-steer situation. There's no easy choice on the packaging, since those fittings are located in a poor position for the CSR.

    I put the car down today to set the ride higth with the springs. Dampers where locked. Then I switched on the controll unit (ignition switch 12V switched). The first thing I noted was the dampers are not quiet. There is a permanent high frequency sound from all 4 dampers. Might not matter in a normal car or race car will see how it does when the engine isrunning and when touring. Did play witht he setting knob which is very simple to handle. Keep You updated after the first ride. PS: car still not finished struggle with getting the 9A9 running.Name:  IMG_1875.jpg

    thks for Your input Bruce.
    Yes I am concerned about closeness of the vertical frame tube and the banjo. Its about 2mm under normal load know. I had Penskes previusly with the same setup without issues and was not aware of the bulky tractive banjo. Thats how I defined the canister tube. I will make a full load test to see ift the banjo touches or not. Let You know.

    Just curious - how much bump travel was that?

    the pictures in the previus post show at which travel I I measured. I hardly can imagine in reality it would travel more and even if it wouldn touch.

    some feedback on my first few 100 km with the Tractive electronic damper and my installation. I changed from very good Penske 3way dampers for the sake of being able to change damper settings while driving to adapt to different road situations. I only do road not race. With the Tractive Dampers from Raceshock's Simon (great Service) I use the same springs I had with the Penske's.

    There is turn press knob to make the settings: I tried this but it is much more convenient with tapping on the display. In damping quality I would say both shocks are equal. One has the possibility to set front dampers rear dampers roll and pitch. It is a great experience when one can change settings during driving and one can learn very fast about the effects of different setting. With the setting on all 4 parameters on full - damping there is no slush feeling and one senses the road very good with the backside.

    THE GREAT thing however is the roll damping in turns. It is such a great feeling when You go into turns and the car stays even!!!!! I feel more confident with these dampers in turns than with the Penskes.
    This is a first feedback after only a few days driving.

    some more feedback after a 850km/3 days blat this week , more and more I like the possibility to adapt damping from perfect road surface to bumpy roads. Even with a setup of full damping it does not get stiff as with the Penskes full hard setup there is still damping. I experience that aggressive driving is less stressful with active dampers.
