My B&G S2s drop the same as S techs to add to your data base ($200-240)
Also H&Rs drop about the same, much lower than what's listed.
Here's my drop

The info some of these manufacturers list for their springs can be quite different than how they end up dropping our Gs. Funny that the H&Rs are listed as dropping less than Eibachs

Some of the brands you list make more than one set of springs for the G sedan. The Eibach listed, for example, is the Pro-Kit for non-X G37's and the part is 6390.140. The Pro-Kit for the X (AWD) models is part 6394.140 and has a drop of 1.9"F and 1.6"R.

Keep in mind those are specifically for the AWD sedans, not the RWD.

depending on how low you may need a rear and front camber kit/arms. Usually with mild spring like the Eibachs you should be fine with just rear (or none at all). Toe is usually a bigger concern and but again commonly fine with small drops.

It's interesting how some Gs w/ the same springs require camber kits to get in spec. and some don't. I'm thinking this is more of a problem finding a good alignment shop as some aren't real good w/ lowered vehicles.
Eibachs, Swift & Tenabe should get in spec without kits. The full F&R kits go for about $525 (the toe kits about $75, Front arms $300, rear arms $200). Alignment should be $100-125.
Labor to install springs & arms can get quite high, call around several places if you don't plan on doing it yourself.

Thanks for the responses. I remember reading somewhere that the Eibachs and Tanabe have the spring rates similar to stock so I wouldn't have to replace the shocks. I want a lowered stance but I don't want to shorten the life of the shocks so I guess those would be the obvious choices then.

I also noticed that all the other brands lower the front more than the rear except for the Tanabe, anybody know why?

I forgot to mention I have a 2012 37S sedan, drove the 37S coupe for about a week and notice that the suspension on the coupe seems more responsive and crisp. What would I need to do to get that same feeling of the coupe?

I'm a newb to modding, so thanks in advance for all the advice and suggestions.

Sway bars. Search for Hotchkis (most popular), Eibach and Stillen sway bars. An affordable, best bang for your buck, mod with the greatest noticeable change in handling.
