I "photoshopped" this image, to see what my car will look like when its dropped. How many inches do you think this is? With the Tein CS Im pretty sure I can achieve this drop, but im probably going to go with the Tanabe NF210 for now- since it seems to be the most economical alternative, and they claim to be ok with stock shocks.

The wheels are stock 17 Chromes, with 235/50/17 Tires.

Does this look like a 1.5 inch or 2.5 inch drop?

 

Here is the original image..

 

i'd say closer to the 2.5 drop

 

I'd say it's no more than 2"

A 2" drop is pretty aggressive, actually. If you think about it, the lowest point on a stock GS is only about 6.5" off the ground. Drop it 2" and you only have 4.5" under there...

My GS has H&R coilovers that were a 1.6" drop out of the box. I have lowered it three times since the initial install; the first two adjustments were each about 6mm (1/4"), so the last "seen" photos of my car reflect a 2.1" drop. (I've lowered it a tiny bit more since then, but nobody has seen it yet).

Anything past a 1.6" drop gets you into some negative camber issues; with my camber adjusters maxed-out to their most positive setting I still have -1.8 degrees of camber. Keep this in mind, it will affect tire wear. Being low and cool does have a price (but it's worth it).

The lower version of the Tanabe springs or the Daizens will get you about that low. Anything lower than that will require coilovers or air suspension.

 

i say between the 1.5"-2" range. no more than 2" in that picture though.

 

do a search for Daizen springs. I'd say you could get that drop with those. Or go coilover route and just dial it in.
