Any feed back on them? How does it compare with the stocks?
Eibach Pro Kit for IS-F

If your referring to ride wise, I don't think anybody has them yet. This is the first I've heard of them being out on the market. As for height wise, a drop of 0.7 in the front and 0.3 in the rear.
Eibach's are known to run more stiff (I've had two sets on both my previous vehicles) then other springs on the market. Its going to be interesting to see who gets them and not only how they look but how they feel
I'm personally going to wait until after SEMA to see if there is a coilover set that is released
Good question. For the amount of lowering that this spring set appears to offer, I don't think they will shorten the life of the factory shocks much at all. You will loose some shock travel though, probably will require trimming the bump stops a little. The pro-kit from Eibach in my experience offers a better look and a slightly stiffer ride for most cars. Also better handling on the street. This is not a spring set I would use if I were looking to make it perform better for autocross or track time. The factory shocks are built and valved to work with the springs on the car from the factory. If you are looking for more serious performance keep an eye out for a coil-over set up with matching springs from a reputable manufacturer.

Well there aren't many options out there for suspension on the IS F at this time. The Tein coilover setups on the other project cars are prototype parts.
I have had Tein and Eibach components on my Toyota and Lexus vehicles. Tein CS for both my 04 IS300 and 07 GS350, Eibach Pro Kit for my 99 Solara SE V6 (w/Tokico struts) and 04 IS300 (Eibach/Bilstein). I really don't have anything bad to say about both. Both spring/shock and coilover setups have their pros and cons.
The biggest thing I dislike about my Tein coilovers, they developed a knocking sound after a couple thousand miles on my IS. Also, the shocks have to be rebuilt after a certain period of time. If I recall correctly, Tein recommends somewhere in the area of 20-30k. The Eibach Pro Kit is a great bang for the buck and they work very well with Lexus oem shocks. The drops are not that agressive and the spring rates are just right.
As far as Eibach, it is a German company but the US headquarters are based here in SoCal. Corona, CA to be exact, only a few blocks away from where i'm currently sitting now and a few blocks away from West Coast Customs.

you might also want to look into JIC coilovers that come out on the market for the F not to long ago
