i just installed some koni reds on my EK with eibach sportline springs...had the springs for awhile riding on stock shocks...but after putting in the koni reds the ride now is like night and day compared to stock, really smooth on the road, no more harsh bumps and good on turns...so i'd go with a good spring and shock combo...something like eibach springs or i've heard a lot of good things about H&R springs, match them with some koni reds, which is the cheaper than the koni yellows but only adjustable with the shock uninstalled, but im going to guess the yellows will be for a more agressive drive and its externally adjustable with an adjustable pearch.
