All I can find is that the 2004 models now carry the Euro suspension, rather than the US spec suspension from 2003. I assume the shock valving is different and the spring rates have changed too. Anyone know more specifics?

 

I'm torn between getting a 04 suspension just for the heck of it to get the rates and to see how it stack's up performance wise to the 03 setup I'm running now. But part of me just says to go test drive a 04 Z to find out how it drives and save time and money
