Simple question- which is the better suspension option for the street? I like the drop of the eibachs from pictures, and the simplicity of the setup, but worry that if the drop is not perfectly balanced front and rear, I will be annoyed. A coilover allows me to tweak this. I'd probably also get the EDFC at some point if not right away (I know this is double the price of the Eibach/Koni option, let's ignore that in your analysis, please).

My sedan is going to be used on the street only as my DD. I want the best street handling while retaining comfort. I seek a modest drop only and will be running 19"s all around.

I'm also considering the KW V3 coilover but that falls behind the SS-P due to lack of an EDFC option.

What do yall think, and *why*?

I would do coilovers in general answering your question. Reason being, a lot of coilovers you can adjust the damping to get the comfort you desire TO A CERTAIN DEGREE. They also allow you to adjust ride height.

With springs/shocks your limited.

Thanks!

As the devil's advocate, aren't the koni yellows c+r damping adjustable? Agreed that ride height is fixed, as I indicated.

Fwiw, the ss-p's ride height adjustment is not really so- its a preload adjuster, which isn't the right way to adjust ride height (you can detrimentally affect jounce with too much preload/ride height). I think the kw's have a true ride height adjuster.... Right?

Yes the konis are adjustable and youll get a mild drop with eibachs. Maybe look at swifts too they should e even better. The nice thing anout springs and konis is you can install them set them and never worry about maintenence.

Pm tvpostsound he just got the eibach/koni setup he might have some feedback for you

I thought the swifts were a bigger drop than the pro kits?

If you want the EDFC option, go with the SS-P.

Front with swift is identical rear is a quarter inch lower for an even drop.
Eibach is 1.2" and .8"
Swift is 1.3" and 1"

nice, thanks! I will likely go with a staggered tire setup which will leave more sidewall on the rear, so I don't mind a little bit of stinkbug. Also, saw a pic of someone's sedan on eibachs in the show me your sedans thread and it looks perfect to me.

And yes, if I want EDFC I definitely need the teins. But are the SS-P's street friendly? Their linear spring rate is right about the final/linear portion of the eibachs' travel. The Eibach initial/progressive rate is half that much so I wonder if it would be a much better street setup.

Also, will the Eibach+Koni setup have longevity or will it suffer from earlier failure than coilovers? I would think it should be the same but I've been reading otherwise here...

thanks

Ull have few or no longevity or reliability issues with the eibach koni setup. Eibach has a million mile warranty on their springs (which youll never need) and koni is right up their with the best of em. They have a grest track record in motorsports too. If they can stand up there theyll be more than fine as a daily. You'll have no issues

Also, the Koni yellows seem to be for the G37 coupe. Do the same shocks fit the sedan as well?

Don't think you need the edfc for daily driving

Nice to have the option of tightening up the ride when you hit the canyons and then dropping it to comfort when commuting or on the superslab. That's why I mentioned it.

I see it as a nice-to-have, not a must-have (for me).

Plus I heard tuning the rear on our rides is a PITA. Do you know if I have to trim the trunk interior at all to fit the edfc stepper motor on the rears?
