One word, Bilstein. If you buy anything else to go with your H&R springs, you will regret it. Yet you won't know why you're regretting it until you pair them with some Bilstein Sport shocks. In all honesty, you should go find a Porsche or BMW board for information about which shocks will pair best with H&R Springs. There aren't many people running those springs on a 240.
I had the option to get some H&R Springs. Instead I bought the Eibach Pro-Kit and have regretted it on and off ever since. The only time I like my Eibachs are when I'm cruising on the freeway at 80. They soak up the bumps perfectly. Other than that, they BLOW.
Man, I should have kept the Bilsteins and just got some H&R Springs. Bah, live and learn....
