Any feed back on them? How does it compare with the stocks?
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 :cool:

I'm personally going to wait until after SEMA to see if there is a coilover set that is released

well compared to the stockies i probably wouldnt touch these... For my previous car I added a 2k HKS suspension coil overs... those would more than likely be worth it

Wow...$8K is a LOT to pay for that kit. It would have to be a significant increase in performance to justify that price.

8k? Where on earth did you get that price? I think your looking at the part number.

The kit varies in price with the lowest I found being $231.00

how would these affect the life of the shocks?
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.

(sidenote: In my previous life I distributed Eibach springs and Koni shocks for 10 years;) )

If you really want to mess with a suspension, put a coil over kit on it. Plan on re-aligning it every time you change the height of the car. Don't get me wrong, coil over kits are the sheot. Not so practical for every day driving though. Great if you track the car 3 or 4 times a year. The kit for the IS-F from Eibach is a PRO-KIT. It lowers the IS-F .7" in the front and .3" in the rear. Not enough to justify camber kits and what not. The ride will still be decent as well. The SPORT-LINE kits that Eibach make are the ones that dump cars in the weeds and cause all kinds of other issues. They aren't making the SPORT-LINE kit for the IS-F. Not everyone will want to spend 1500.00$ - 3000.00$ on coil overs.

I have them in my car and just drove from York, PA to Houston, TX 27hrs and also around town for a couple weeks with them in. I paid $247 bucks for mine and was charged 150 bucks to put them in by a shop here in York. Now I don't think I'm a typical consumer because I LOVE handling and LOVE feeling the road. It is not any harder of a ride then stock in my opponion BUT I can surely take a corner faster and harder then stock, that is for sure. That is what I look at, handling in the corners. EIBACH makes a high quality product and they R&D it well for the best suspension performance. For the price and the look, you really can't beat it. No, it is no full coilover but you are going to spend another 1500 bucks for that. This does the trick well because the stock shocks are performance ones to begin with. They are engineered to be lowered. There is my two cents on it..haha.

I respect your opinion and input and appreciate your insight, but a couple things I would like to touch on. You stated that for the money the Eibach setup can't be beat but why would that be an issue for people spending $60,000 and up for a high end performance sports car? We are talking about ride quality here, not what tire shine product is the best for your 19 inch rollers. And your desire to have better cornering when altering suspension wreaks of "captain obvious". Isn't that why one would upgrade suspension, to improve cornering ability? I will not endorse Eibach and in my opinion hold KW, Tein, and Tokico as better options.
To answer the question you speak of. The ride quality is AWESOME, and I think I have put more miles on my IS F lowered to know in all aspects. It is great on the highway, street, whatever. When you look at a suspension for your car it is ride quality, and handling, that is why you consider this type of upgrade. Well, no shit, I was just saying I put it hard into the corners and it responsed like I wanted to see. Not all spring companies can say that. I used TEIN springs on a couple of projects and they didn't respond like these Eibachs did in the corner. I seriously test a product because I drive my cars hard as they should be driven in my opponion. The TEIN springs I just used where in my 08 Altima Coupe Turbo and it was soft in the corners, not to impressive to say the least.

KW, TEIN, B&G Coilovers are BAD ASS, I know first hands in other applications. The Eibach coilovers really are not in the same league as those guys. But those are coilovers and in a different league then just a spring. My camber is perfect so I'm happy with the end result with EIBACH springs. Tokico is just a shock company and doesn't make a spring product so I can't compare them in this instant with the IS F. At the end of the day, it is all personal perference isn't it?

That's great insight Brian. I can't wait to see the final result next week in Vegas. Hopefully I can catch you there and say hello. :thumbup:

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 :D.
