Eibach lowers the AWD 1.9"/1.6" and the RWD 1.2"/0.8".

Big difference for the AWD guys.

I got this info from their websites.
Not a big difference, the end result in lowering of RWD and AWD is essentially the same with Eibach. The AWD cars start higher, thus the total amount lowered is higher to achieve the same drop as a RWD car. Trust the pictures not these companies terrible measuring data.

Swift lowers the AWD 1.3/1.0, Eibach lowers the AWD 1.9/1.6. Thats an additional 0.6' front and rear. That's definitely substantial.

If you're saying there is a substantial difference between Eibach and Swift, with Eibach being lower, I agree.

I was under the impression you were saying the Eibach springs lower an AWD car more than a RWD car. This statement I would not agree with.

Very interesting to say the least. I take your word for it as I've never seen a G(in person) with either Eibach or Swifts. The MANY pics I've seen online seem to suggest to my eyes that the front drop is pretty close to the same on both, while the rear drop on the Swift Sports seem to be a bit lower. A few people have even said that the Swifts look 'uneven' front to back vs. the Eibachs, I surmised due to the rear drop being lower on the Swifts. And the pictures I've seen seem to back that up. I actually had purchased Eibachs that are specific to the IPL, which is what I drive, but returned them(minus a restocking fee ) after talking directly to Leonard at Swift Springs in Cali. He told me the Swifts Sports #4N906 were designed and tested first ON a 2011 IPL at their Cali location. Which is another reason I decided to go with the Swift Sports instead. Having them installed this spring...

Whatever "sag" people think they see on my rear with the Swifts is an optical illusion... The distance on the rears from the ground to the bottom of the wheel well is 27-5/8"... the same measurement on the fronts is 27-1/4".

Here is my 37xS with Swifts after about a year. . .

and the picture is taken from the ground which would only accentuate the wheel gap. . .

I think the fact that there is a little gap on the front wheel makes it attractive. Not what I wanted for my application, but looks nice nonetheless.

PERFECT! Unless you choose to go the coilover route for more $$$$ to get the drop exactly the way you want. That is how I want my IPL to look after my Swift install. Great pic.

I just went out to my car to take a matching angle reference shot for the Eibach springs.

that looks awesome, perfect comparision!!

just to be sure are those the Eibach springs specifically designed for the AWD coupe? and tires have the same diameter?

There may be a +/- 1% between the tire sizes. I have the Eibach springs designed for AWD applications installed.

Just to be clear, both the red and gray G's are the AWD versions, correct? Although, the Swift drop for the AWD is the same as the RWD models (1.3" F, 1.0" R), and substantially less than the Eibach AWD drop (1.9" F, 1.6" R), the drop on the rear looks fairly close on both. One would think the Eibach drop should be lower but it appears the Swift car actually is a tiny bit lower on the rear. The front unquestionably looks lower on the Eibach car, as it should based on the paper 'specs'. Moral: I'll simply trust my own lyin' eyes. Great picture comparison and two awesome looking cars guys.

Yes, both cars are AWD. Take another look, Ryne's rear is definitely lower than mine. On mine you can see the top of the rear tire, whereas on Ryne's its tucked. You really have to follow the contour of the tire as the top is lost in the shadow.
