I've decided I'm going to order the H&R cup kit for the Crossfire. It's a package of shocks and springs to lower the Crossfire and make it handle better. It is made for the SLK but should fit the Crossfire. The thing is that it drops the Crossfire 1.9" in the front and 1.7" in the back. That seems REAL low to me, but I think it would look awesome. That's so low I think the front wheels might even be tucked. I'll have to adjust the camber as well. I was thinking of going the Koni/Eibach route like Andrew, but I have heard a lot of good things about H&R. Also, does anyone know of any good shops in NJ that will install these? I have everything I need to do it myself, and my brother knows how to do it, but I want someone to be accountable if something gets screwed up.
Here is a pic of a C230 with the kit:
