My initial feel is that the Dinan springs drop was too minimal (only around 1/2 inch) and in the Comfort & Sport mode I cannot really tell much of difference vs. the stock, i.e. still very comfortable ride with some body roll on corner. I have not tried in Sport+ mode and driven the car too aggressively yet.
Anyone else out there with Dinan and can share their thoughts, thanks.
Any noises (at all) after the installation? like taptaptap sounds?
