I have Tein H specs...I can't be happier. No bounce, excellent performance handling too, no bottoming out, I have so much fun driving my car I take it on the road instead of a rental when I go on business trips. The drop is clean, agressive without being slammed and useless on most urban road surfaces. Cornering is crisp (I have a new suspension and braking system too) and under control even at high speeds (say taking a 30mph turn at 70+). I have owned H&R, Neuspeed, and Eibach, these are better because they are not that stiff. Car handles like my ex's 540i. I mean the Tein are better because they are not as stiff.
