    Information needed from people that put CTS-V suspension on a CTS 3.6L

    So I ended up buying the complete suspension for a CTS-V (FE4 shocks, Struts, V-spring, front/Rear Sway Bars with only 22K on them!!!) and waiting to get them installed…

    My questions to the people that have done this modification is;

    Did you have to modify anything to the nivomat shocks for ride height? Since I am using the V-Springs I would think that I just install as normal…? But if I lowered it I would do the WW or Mighty Mouse mod to lower in the rear, right?

    After the install I need to do an alignment… did you need the camber kit for alignment or not?

    Is there any other unforeseen items that I might run into or cost to perform the installation of the complete kit???

    Thanks

    using all the cts-v components you will be fine.
    buy new sway links and you may want a alignment.

    I've only put sway bars in. I like the increase in apparent stiffness in cornering.

    I have the soft ride suspension option. Just how much harder will the ride be if I go whole hog and put in all V suspension parts?

    I am soon going to find out how stiff it will be by going "whole Hog" out. I am excited to find out, i heard it is a bit more harsh. But the handling is a good trade off.
    wait to see

    Re: Information needed from people that put CTS-V suspension on a CTS 3.6L

    ya... its stiffer. maybe im a oddball but i dont think its that stiff.

    i test drove a fe1 or fe2 cts before i found mine, and honestly i hated the suspension, i almost stopped looking at the cts..glad i discovered fe3 then the V shocks FE4 with eibachs.

    im also one of the rare people who hate the feel of stock rims and love how 20s ride.... i would rather be on a dirt road on 20s than smooth pavement on stockers...
    weird..

    If you ever need an alignment, you do not need a camber kit. The camber adjustment is done on the lower control arms. The bolt that holds the control arm to the frame is slotted so the arm can move in and out a bit.

    I just started my coilovers today with plans on a suspension how to. I will also be showing the alignment slots in the frame because I have to make them a bit longer because I will probably be a bit lower than the factory will adjust to. Stay tuned for the write up.

    That is good to hear that I don’t need that camber kit... I was curious cause I seen the "Eibach Camber & Alignment Kit 2-corner" for use on the pro and street kits. Am I wrong for thinking that you are required or needing this for lowering the car? Or is this just another thing to spend more money on?

    Eventually I will lower the CTS, and did not know if I need these bolts for the +- 1.75 degrees of play over the stock ones?

    Re: Information needed from people that put CTS-V suspension on a CTS 3.6L

    I just finished installing FE4 shocks, a mighty mouse kit, V sway bars, Hotchkis lowering springs and a shock tower brace. The car originally had Fe-1 suspension, the ride is some what firmer but nothing bad unless your on uneven pavement, then your feel some harshness. The car now sits about 1 1/4" lower all around and the guy that did my alignment took the camber settings to the max and the car is still out by about 1 to 1 1/2 degree on every corner. Has anyone out there had any luck with Camber kits? I read somewhere on the forum that someone purchased the Eibach kit and that it didn't work out for them.

    Re: Information needed from people that put CTS-V suspension on a CTS 3.6L

    Can you post what your alignment numbers are now? Also can you measure the distance from the center of the wheel to the bottom edge of the the fender for all wheels. It'll give us a reference on how low is your ride. And like Blayne said the control arms bearing ends go into slotted holes in the frame where the adjustments are made. It could be made at least a 1/4" longer to give you your numbers (if you ride isn't slammed to the ground)
    -1.2 to -1.3 camber up front is good and -1.5 to -1.8 camber for the rear. Go with zero toe up front and 1/8" to 3/32" toe in on each rear wheel.

    Those bolts on ebay may work to give you that little bit more. When I did coilovers, the best I could get was -1 degree all around. That was ok with me cause that's where I wanted it for better corner handling. If you do some aggressive cornering I would try to stay at -1 degree. Your tires won't wear much at that setting. Try the bolt. I will be trying it too cause my stock ones are all seized up

    If I did D2 coilovers with v front & rear sway bars. Would I have a noticeable harsher ride than I have now. Im currently on FE1s

    The sway bars don't give you the harsh ride per say. They just stiffen the car up on side to side movement ie. cornering. I did the D2 coilovers and they have a great ride. And I say this living in an area with horrible roads. Nobody can tell I have coils on by the ride. The performance side of them is great. Awesome ride!!!

    ----------

    The D2's with the v sways would be awesome. I am currently looking for v sways!

    As Iceman asked, what are the actual alignment numbers now, and what are your actual ride heights?

    I'm running about -2.2 up front and a little more in the rear with no adverse tire wear issues. -1 is about the minimum I would want if I had any intention of driving a car aggressively. Improper toe settings are much more likely to cause uneven tire wear.

    Re: Information needed from people that put CTS-V suspension on a CTS 3.6L

    Has anyone on here swapped in the A-arms and brakes (and thusly rims, etc) from the CTS-V into the V6 CTS? The CTS-Jr is lighter so the Vee-car parts would be bigger and stronger direct-fit upgrades. Would you have to swap differentials to use the CTS-V rear hubs/brakes? Do those hubs only mate to the Vee axles? And those, in turn, only mate to a Vee-car pumpkin? I guess replacing the CTS-Jr diff with the Vee 3.73 G80 would be nice because you get the lower gears. The only other way to get lower gears is to go to the euro spec differential. And it doesnt matter if you are going for a V6 euro spec (3.93, I believe) diff or a Vee pumpkin, its a $1000 either way. I do not have money to do it all at once, but since I am upgrading to Vee-car sways/springs/FE4's, I might as well keep it going and replace the hubs/control-arms/brakes with the beefier CTS-V equipment. Can anyone tell me exactly what would be needed? Sorry, I dont mean to hijack this thread.
