From the little research looks like KYB is the only option. Are there other options for the Sedan?

Edit: I don't want coil-overs and I already have Swift springs.

 

Koni Yellows

 

I believe the Konis don't fit the sedan.

 

That's not correct.

Here is my thread where I installed them on my sedan:

BlackBetty has them on his sedan too, as have a few others.

The misconception that they don't fit the sedan is twofold, first, Koni doesn't list them, but does the 370Z and G37 coupe. And two, someone, a long time ago, mounted them incorrectly and claimed they raised the ride height.

The Konis come disassembled, and it's possible, if not easy, to mistakenly assemble them with the lower spring perch mounted upside down, effectively raising the car. These aren't my pictures, but they illustrate the right and wrong way to assemble the Konis.

Swift + Koni is an awesome combination

 

I think they don't fit awd that's why more people don't run them.

 

The fronts don't fit the AWD. But you could gut the AWD fronts and go the insert route like the WRX and STi guys do.

 

Thanks Lego!!!

 

Mr Maniac could you please more information on these "inserts" you are referring to? Thanks!
