the handling is fine and no warping also with high speed, but if I slow down slightly (also if i do it hard) from 160km/h to 100 km/h the whole car is vibrating and it is also hearable.
I also feel this vibration at my break pedal.
But the steering wheel does not pull.
I also can notice this vibrations by lower speed slow down, but only very little feelable. Hearable it is just at higher speed, and there you hear it very loud.

The dealer also changed the brake fluid after the lowering, maybe there was a problem? or the suspension adjustment? or a not right fitting wheel?

does anybody has an idea what this could be?
some told me, it could be the brake disc but i think this would be a great coincidence directly after lowering, or?

I have on Monday again a date with the dealer.
If you haven’t already, start with an alignment. They need to be realigned after a spring install after they have settled.
