i have h&r's 1.2" drop and i have no issues with them. the ride is a tad stiffer which make for nicer cornering. I have the factory 20" 214 wheels on. I think a lot of people are feeling the stiffness more so because of the factory run flats. I recently changed to my snow tires (18" NON runflats) and it's like butter. No harsh ride at all. Snow tires are Pirelli scorpion ice/snow if you must know.
can't wait to burn through the 20" run flats and go to normal tires.
