thanks. From the thumbnail (with his thumbs down) I was worried he didn’t think it helped much. But that is not the case.
tl;dw he said it helped a very noticeable amount — not 100%, but maybe 40-50% — and noted that no suspension is going to be 100% perfect over bumps. So a big improvement but probably not as much as air suspension, which is rumored to be coming from Tesla. He also said it drastically reduced body role, which was an added bonus that he really appreciated. And he noted it’s very adjustable - both soft vs firm (e.g., for the track), and also ride height.
