Question on drop

[Hiei GT-S]

How much is a finger drop on a GT-S with stock 16" wheels. I got the ground controls so I dont know how low they are. Im getting the AGX struts and was wondering if I should raise my car so I dont blow them. Anyone know the drop on regular springs that leaves a finger gap, Im guessing 1/2 an inch gap all around.

on stock springs you can there is about a four finger gap. on the trd springs i just installed i can barely fit two fingers all around.
