G37 Coupe Eibach Springs on Sedan? Anyone? F 1.2 R 0.8

You're right ... most likely a liability issue. A few months ago, I asked about 2nd gen G35 sedan springs being used in the G37 sedan. I was told they will fit, but they would not recommend doing so because they were not tested for that application.

i agree with you guys that it must be a liability issue.
I didn't know the weights of sedan to coupe were that close, this might be worth a shot.
only problem i forsee is this:
it drops the COUPE 1.2 and 0.8, from its stock ride height. How does the coupe's stock height relate to the sedan's? if the coupe's stock springs are even slightly lower than ours, that difference will be in addition to its posted drop.
It really comes down to this...who's willing to try and experiment this setup?

Fronts are easy to compare, there's minimal difference, the rears will take a little legwork to factor in the different tire sizes.

Wes, you and I have talked quite a bit recently about the mild drops...specifically the use of 370Z springs. Since we have so many choices already available for mild drops(Impul, NF-210, 370Z springs) I'm curious what you're looking for. I'm assuming you want a mild drop but the performance of a stiffer spring. Are you thinking about getting rid of your eibachs?

btw, is there any benefit with physically comparing stock springs of G sedans vs stock springs of the coupe? To get a feel if the eibach coupe springs will work? At least length wise of the springs.
We got Ian, Eug and Johnny for stock springs (I think you guys kept them...right?). Then im sure I can find someone in Toronto with a coupe who still has their coupe springs.

Tanabe's give a really good mild drop. But im afraid to get the saggy bum look. I know 2Gornot2G figured it all out with the right part #. But Until someone else gets the same result as he did. I wont go for them.

Touche... your probably right. I looked at the tanabe website:
http://www.tanabe-usa.com/springs/sp...tions.asp?id=1
the drop is 1.4 all around. Listed price is $ 330 bucks.
Eibach drop is listed at F 1.4 and R 1.3. Ground clearance of 4 inches.
I think I gotta ask 2GorNot2G whats his ground clearance is like to fully compare.
EDIT: Oops!! I looked up DF210!! Not NF210!!!

F 1.0 R 1.3
Although 2GorNot2G's drop looks perfect.. what I dont understand is.. why is it 1.3 at the rear? Not even all around?

That's exactly why I didn't buy those springs. The front has more wheel gap than the rear, so why would they make the rear drop more? In my opinion they should drop F1.3 R1.0...even that would have been too much drop for my taste, but I'm also 38 years old for what it's worth.
