I've got Eibach Sportlines on mine, chose them over the H&R as I feared that the H&R might be a tad too low for my liking. I like the drop and it is low enough for me yet practical. When I first had them fitted the ride quality didn't feel different at all... it was only after a couple weeks that I started to feel the lumps and bumps in the road.
But to be honest the overall ride is still ok and easy to live with.
