I was looking around h&r's website and decided to look up the crossfire to see if they had any cupkits available for them yet(mightyjlr was talking about getting springs/struts).. this is what i found:

31020-1 Chrysler Crossfire Typ ZH
front axle45, rear axle40, 31020VA1, 31020HA1

Now here's where it get interesting, i looked up a slk and found this:

31020-1 Mercedes Benz W170 (SLK), up to 260kW
front axle60, rear axle40, 31020VA1, 31020HA1

Same part numbers, only difference is that front axle designation. I just thought i would share with you guys, if anyone is interested in a h&r cup kit..

edit:added a picture in for clarification
