Lowering Springs Comparisons

Orionx1

Hey guys, a have a couple questions for those that have installed lowering springs on their Nismo. I have an 09 Nismo and I love the way it rides and handles, but I want to close the tire to fender gap by about an inch, front and back without changing the ride / handling too much. So with that in mind, and based on the spring specs in “Trips” post, it seems the Eibach Pro or Tien springs would be the way to go (?) – due to the similar spring rates.
I understand that the Nismo stock ride height is about half an inch lower than base or sport models. Should I then assume that a 1” drop spring will result in a half inch drop for the Nismo due to its “pre-lowered” state(?)

Any positive or negative feedback from other Nismo owners with spring kits, ride / handling, general drivability etc would be greatly appreciated.
