I have looked into the Koni FSD as well however, I've seen threads on them having leaking issues on different forums. I have also looked into Eibach Pro-Kit w/ Koni Sport (Yellows).

Im running OEM Style 249 wheels 19x8 ET14 245/40 F and 19x9 ET14 275/35 R (yes I want a little meat on the tires for once in my life and these compare in overall height to the 245/35 275/30 that alot of people are running on 20s). I recently purchased a set of Eibach Pro-Kit springs and want to put them on but cant decide whether to get a factory sport suspension (approx .7" drop) which most say isnt worth it as its not noticable or just install the Eibach Pro-Kit (1.2" drop) on top of my factory non-sport shocks. Now I have read where people have done this before but most people suggest that it will blow the stock shocks/struts fairly quick but also have read on the Eibach site as well as ModBargains site that they are engineered to run with factory shocks. So I guess here are my MAIN questions:

* Would swapping out to factory sport suspension even be worth the time/money?
* How long do you think the stock non-sport shocks/struts would last with the Eibach Pro-Kit?
* Do you think I would rub with either setup with the wheel/tire combo I have?

Like I said in the subtitle bring all your opinions! Ive done the research and just want REAL WORLD EXPERIENCED OPINIONS to help me decide, hopefully maybe even somebody running a similar setup that can verify information. Thanks in advance for any help

My advice...decide and do it once. I made the mistake and changed it a few times...very expensive (labor).
Good luck.

He decided to go with Eibachs once he saw my car go from non sport to sport springs. I saw him the day after he lowered his car and I remember thinking that it was not that much different than mine with the sport suspension, but it had a nice rake to it. His front looked a tad lower than mine but the rear looked the same. He says it had settled more than when I had seen it. He too has had no problems with the stock shocks. If I had to do it again, I would go with the H&R sport springs, but he insists that if I see it now it is the perfect drop with the 124's.

The shocks didn't go right away but they did go within 6 months of me installing the springs on the factory shocks. Once you blow out the shocks, you will be bouncing all over the road. The same happened to my brother on his G35 Coupe. If your going to do it, do it right. Get some good shocks and just do it all the same time.
