By the way, where are you getting the 2.25" drop spec? Is that a spec from the springs that you have now? If you're going back to stock tire diameter (with the new 16" wheels) then you'll actually have that 2.25" drop from the springs, if that is what they have.

If you've actually measured the drop as 2.25" with the 17s, are the 17s are larger tire diameter than stock, then the springs obviously have to be more than 2.25" by themselves.

I'm just trying to figure out what parts that you have on the car are actually contributing to the drop spec that you listed.
