I would spend a little extra and get the AGX struts. A little stiffer, but would be better for that amount of drop of those springs. The GR2s are basically a stock replacement. I wouldn't wanna go that low on them, plus the AGX are adjustable.
Also, this is quoted from one of the mods from the suspension part of this forum.

This is what it looks like with stock rims 205/60, and AGX / Eibach ProKits

With your rims you'd be much lower.
