Yes the ebay and FM v-maxx are different(spring rates and possibly valving), and FM should be receiving a shipment within the next few weeks (before the end of the month according to Keith). I just ordered some longer springs from FM, so I'm currently waiting for that shipment. My personal thoughts are they are better than my stock MSM suspension, but with the original v-maxx springs I couldn't raise my MSM up enough without coil bind. Once I get the longer springs I think they will ride even better as I won't be on the bumpstops nearly as much. For a lighter weight NA miata I think the springs that come with the package will work great for slightly lowered daily driver that might see an autocross or two.
