"Mild" drop + "ride quality" means "DG springs":

Take manufacturer claims such as "developed to match stock dampers"
(as known from VWR/Racingline or others) with a grain of salt. They may
have been developed with the stock dampers in mind, but that does not
mean they're perfect match for them. Being perfect match does require
both appropriate spring rates and travel. Spring rates may still be in an
acceptable range, but travel definitely isn't. With VWR springs you will
feel a need for uprated dampers sooner or later.
There are so many people on the Mk.VI GTI forums, who've been happy
with VWRs + stock dampers in the beginning, while two or three years
later they realized it's far from being ideal, feeling underdamped or even
crashy.
I know, some people won't appreciate to read this, but I prefer to be
honest.
DG springs still match the stock dampers best, since they're closest
to stock springs both in spring rates and remaining wheel travel. If you
prefer more drop, you should really really seriously consider uprated
dampers (Bilstein B8, Koni Orange etc., but not Koni FSD).
