Well the problem is, there is a height issue with some Nismos. The front wheel arch sits at or near 28". OP measure your wheel arch. My Z was at 27.5" and once I put on my Nismo shocks and springs it's at ~28". About a half inch increase. So I can see why you want a "Front Drop Only"
You could get some Springs with a "minor drop" and throw them on the fronts and see how it handles. You could also install the rears and then add a spring mount spacer to lift it back up to OEM height. Problem solved, and the rear is super easy to do. Even a caveman can do it.
