I only lowered my suspension a bit, more for the benefit that Eibach Pro-Kit give to the ride: more comfort and lower body roll. For me they're awesome for the value.
If you don't want to lower your ride you can think on some Koni FSD 2100-4090 when your dampers are blown out.
Only now I've noticed that you're on the 4th HU!
I think you'd love a RNS-510 with DAB. Just me saying...
Better bushes and the ALK will make a big difference to improve your ride.
