I've been following this thread for a long time but I never put that much time on understanding suspension frequencies. I have been fighting for 2 years with my Yok CAL3 /3.1 trying to find a balanced setup. The car just looks very unbalanced. Found this, and thought it was time for a change.

The car is really twitchy up front with very low to zero chassis roll where it looks to wheel bounce all around, similar to having a super heavy front shock oil. The rear goes the same direction. Near to 0 roll to the eyes and losing grip pretty fast on corner exit.
I think I'm going back to factory setup and start setting up a correct spring fequency. I may upload some videos that could be helpful for everyone here.

Lots of info from here to there and many more setup adjusments makes it even more difficult. When axle heights and pills come into play make it even harder
