    Re: lowering springs for CTS 2008+ AWD

    I have no interest in lowering my AWD sedan, but I have alot of exerience lowering cars for road racing and lifting 4x4s for off road use.

    If the rest of the suspension is left alone, includuing the bump stops, the drive lines will not be over extended or over angled (pinched) since the overall travel distances will not change. However, your available up travel over bumps in the road will be reduced. This will result in smaller bumps causing the suspension to hit the stops. This will make the ride very rough and upset the handling when the bump stops are contacted. Stiffer spring rates can help with this some, but then that just makes the ride that much more harsh even before you hit the stops. To truely lower it right without effecting up travel vs down travel and make handling improvements, you will need to get slightly shorter shocks as well as get shocks valved for the spring rates you intend to use. Variable rate springs make this nearly impossible. The CTS V has the magnetic fluid shocks which can be tuned through programming and can be made to match a wide variety of sping rates.

    If your lower jsut for looks, then I guess none of this matters. If your lowering to make handling gains, know what your doing before you start or you'll probably just make it worse rather than better.

    Re: lowering springs for CTS 2008+ AWD

    Well I contacted Eibach's 1.800 number (1-800-507-2338) and spoke with a representative and he mentioned to me that they have just not tested a Cadillac with AWD and so they don't have the spring compressions on file. My guess is how much the springs will lower with possibly the added weight of the AWD or transfer case in the front and as well in my case the bigger 3.6L. I noticed that a few on here have tried it and i am going to lean this way as well. I have the FE2 suspension so I am confident it will work. I don't believe it has anything to do with the drive train or other components in speaking with him. Just not statistical data.

    If You have the FE3 suspension it sounds like from the website you will need non self leveling dampeners if equipt. I will attach the link and comments as well.


    PRO-KIT Performance Springs (Set of 4 Springs)
    # 38136.140

    Front: 0.8 in
    Rear: 1.0 in
    Footnotes: Vehicles Equipped With Self-leveling Rear Dampers Must Replace With Non Self-leveling Dampers Such As Fe1 Or Fe2 Dampers To Properly Lower.

    Re: lowering springs for CTS 2008+ AWD

    So I called Eibach as well on these 11-12 suggested models and they stated that they are still in the prototype phase possibly available near the end of this year... maybe... The main reason being is that they don't rarely see to many AWD down in southern California. I would imagine if they became available they would work for the 2008 and up as well, but maybe someone else would know more about that. I believe the spring setup is still the same. They will not market until they have certified there testing with the final conclusion. He didn't say that they wouldn't work just haven't been tested.

    So my conclusion is vehicle weight in the front. Would anyone have knowledge of weight difference. ie. 3.6L and AWD.

    Thoughts??

    Re: lowering springs for CTS 2008+ AWD

    One other thing i must add quick as well is that the part number PRO-KIT Performance Springs #38136.140 is for the 3.6L as tested so the only other vehicle weight in my opinion would be the FWD set up in the AWD.

    Phewff i'm tired....i'm gonna stop typing. lol

    I have a 2008 CTS4 AWD. I've been reading forms. I see that they make a AWD kit for the 11-12 models. Is there a kit for my car yet or is everyone going with a different kit that still works?

    Hey Cyrus, i have the same year, make, and vehicle as well and the guys are going with the EB38136.14 model for the 2008-2012 model

    The EB38147.14 model of Eibach is listed on there website for the 2011-2012, but don't exist yet as indicated in the top thread.

    Conclusion EB38136.14 is what will have to be used. I am lowering it tom and will let you know how it goes.

    Re: lowering springs for CTS 2008+ AWD

    Late reply...

    Hey Guys, I just wanted to let you know that the springs worked great with no issues at all. So those of you who have the AWD with either engine will not have to worry. It made for great handling and even better in the winter conditions. Just make sure you get the wheel alignment done after.

    Sorry i don't actually have any pictures and actually just sold the car after having it this summer and into the fall/ winter. Because of my love for the CTS i sold the base model and picked up a 08' Premium (base>luxury>performance>premium). The rare burgandy with the gun metal rims. I will post picks shortly on my profile.

    ----------

    Hey Cyrus, yes it was the RWD kit purchased!!! They worked great no issues.
