Hey guys. I have searched, but I cant really find anything definitive about this. I have a 2010 G37xS sedan and I am looking to lower it. I don't want the ride to be too stiff or uncomfortable so I am just going to go with springs instead of coil overs. Also, don't really wanna drop the extra $$$ on the coils. I have seen a couple pictures of guys on the Eibach 6399.140 springs and I think they should be exactly what I am looking for. Now, obviously once I install the new springs I will need to do an alignment. My question is am I going to need a camber kit (front, rear or both) to run these springs? If it will be just slightly out of spec I probably wont worry about it, at least at first. A little extra camber will be sportier anyway. But, if its going to be way out and eat my tires up I am going to get the kit. Anyone have any experience with this set up that could offer some advice and maybe post their before and after alignment specs? Not going to be dropping her for about two months, so there is no rush on this. I just want to go into it with as much knowledge as possible. So, as always, any advice will be much appreciated.

 

YES,, You will need a camber kit, I thought not also, but went to get a alingment on saturday after I installed my wheels and I'm out 2% front and rear. Toe is fine but the camber is out and the stock set up doesnt allow for enough adjustment. The ride will not be bad just stay away from big bumps.. Typical lower car driving.. LOL Look like you are drunk.

 

ANMVQ was your camber out by 2 degrees total or 2 degrees more than spec? Cause the max end of the spec is -1.16 in the front and -1.42 in the rear. So being out by 2 degrees total, while pretty aggressive, would not be too horrible.

 

No one has any other input on this??? Come on, I know some of you other sedan guys have used these springs! Even if your on other springs that are close post some before and after alignment specs. It would really help me decide what route I want to go and I would really appreciate it!

 

I'm on The Eibach Pro Kit with SPL (not SPC) rear camber arms. My toe was acceptable (so I didn't install the toe bolts), as was the front camber since the drop is minimal. My rear camber is now close enough so there is isn't any visible wear but could be adjusted better if a tech actually gave a ****.

My ride isn't wasn't much different from the OEM "S" ride. I would say about 5% to 10% stiffer after springs and a little more stiff after Hotchkis sway bars (which are awesome). The only concern I have is that the rear looks lower than the front and with the Ark exhaust I do have to approach my driveway at an angle.
