It says it's 30-way adjustable.
The HKS Japac website says the HipermaxIII coilovers are adjustable from 0mm to 49mm drop.
I've been reading about the HKS HipermaxIII on some of the import forums, and a lot of owners are saying it's the best street coilover set-up they've used. Not as good for the track as other coilovers, but best for the street and light track use. One guy on the 350Z forum swapped from KWV3 to the HKS.
