i put bilstein b6 edc shocks with eibach springs on my f80 m3, and it really helped with the dampening at speed and made the ride on a 30 series sidewall far more tolerable on street - but this wasn't hard as the oe sachs shock bmw use are terribly stiff in initial travel
i'd be very interested in doing same on RS3, though iirc from my old car, the mag ride wasn't that bad - less weight over front axle should help dampening on the FL too
