I had the H&Rs with the bilsteins and I loved the tight handling on smooth roads but damn it was so crappy on every other type of road. Small bumps and cracks felt like sinkholes and the hard bottom out bang was an embarrassment on a BMW. I was on 18 non runflats too. It felt like a 1987 IrocZ. I got rid of the H&Rs and picked up the Eibachs and wow what a difference. No comparrison as far as ride quality goes. Another added bonus is the front rake is also gone.
