Are the spring rates the same for the non-sport spring and X model springs or are they different? THe "X" seem waaay softer, but just thought I'd ask.

 

Well, the X sits 40mm higher, thus it may have a bit more body movement. The Springs themselves seem stiffer than the non-sport, at least that's my feeling.
Gs could use better dampening<sp>. The X is no exception, it's a cush setup from factory. If I keep my car I'm going with something stiffer soon.

 

there has to be stiffer springs in the X compared to the RWD cars b/c the X is so much heavier. With that said, I am sure they are just stiff enough to offset the extra weight of the X.
