looking for new suspension

[rstylez]

Hello all
need help for my 2007 m45 sport
I was looking into Eibach pro kit for springs and also looking for shocks and struts
wanted to do koni yellow adjustables but they dont make for my car.
Any suggestions for a setup?
not interested in ground control coilovers since i dont plan to track my car.

What ever you do you will need to make sure you get car set up properly. I lowered my m35 using Tein Stech and I have terrible tire wear and can not properly align the car anymore. Lot's of people have lowered their cars and have not run into the issues I have seen. In order to get proper alignment you will need to either get the camber bolts kits(drilling is required) or get a new set of upper control arms, these need to be adjustable. I am putting my back to factory spec's I am replacing my front and rear struts at the same time.

My car handled the same with the stock height as it does in the current lowered state. The best results are by far- going with a complete coil over suspension. Cost more, easy to tune and you get all new dampers with excellent springs etc. Don't cheap out, you will regret it for sure. Good luck

merling2 - are you going back to factory parts both for the front and rear? if not, can you share what parts are you using; mainly on the rear? thanks

[merlinq2]

factory all the way around. ordered them on line they are in transit from arizona as I type. I have the factory springs, kept them in the garage when i had the stech's installed, does that help.

so-front struts are oem same for the rears

any low drop and front camber arms are needed to get back to oem alignment specs.

Dang, so you are saying the Tein S-Tech springs are that bad?? I have a set sitting in my garage, and for now, have no plans to use them. But if you are saying they are that bad, maybe i'll go ahead and push them off on someone else.

Do you think it had something to do with your car being an X model, or possibly old / worn shocks & struts.

And yes, we all agree, a coilover suspension is always the best way to go, other than factory.

the problem with front camber arms is that they cost too much money (over priced IMO)

but they should be installed at the same time when installing lowering springs in order to save time & money

[DoN_BLaZe34]

Do the Eibach control arms not fit on the X? Merlinq, any reason you didn't purchase them?

To be honest, they are fine, the ride is okay and the car handles about the same. To truly optimize the ride and get the most out of the drop and improve the handling, you will need to install the camber kit. The springs are very nice and the quality is excellent.

It is hard to say if the ride was degrading over time and that the installation of the springs exposed the weakening stock suspension- can't tell for sure. I will say that with out the camber kit I developed a really odd rebound in the front right wheel. Going over a bump the steering wheel would pull to the right side. I think this a symptom of a worn strut. Having said all that; I would like my car to go back to the stock ride height, I feel that the stock ride is more refined and demonstrates the cars handling better.

Also, I might sell it this coming fall; so it make sense to get it back to stock so I don't have to deal with the issues that come with trying to sell a car that has been somewhat modified.

Is the fact that my car is an X contributing to the problem; maybe not qualified to answer that other than to say I am disappointed. I do like the way the car looks with the drop - should have been designed that way to begin with.

IMO, I would spend the extra money and get the camber kit (new upper control arms is the right way), it will make the car feel better.

Good luck

Not sure - I think I read somewhere that they do fit. I think there is a link here somewhere that answers that question.

I was trying to keep the spend low so I figured dropping 300 bucks on springs would allow me to decide if I wanted to go to step 2. So I based my decision on cost. In the end if I wanted a lower slung car that handled better I would have found a 335i. So for me it was a fairly inexpensive and easily reversible experiment.

Does that answer your question?

all stock oem parts huh? where did you order and what's the total cost include shipping?

[merlinq2]

Front struts are coming form infiniti parts usa. Shipped parts -
1 of : (Item 1) 2007 M35 X Left Strut $172.88 Shipped
1 of : (Item 1) 2007 M35 X Right Strut $242.09 Shipped

Shipping to Tonawanda Ny. $16.86= 431USD

Rear shocks I bought from a local Infiniti dealer in Mississauga Ontario - those cost me $300.

Total cost $731. Taxes , shipping and handling- Only other cost is fuel for me to drive down to Tonawanda and pick up the parts.

[cruzad3r]

so i called my dealer in hartford ct about the suspension refresh and they quoted me 900 for 7 hours of labor and 1300 for parts. on top of that, you tag on 6.25% tax

YEahhhhh - anyway, merling, why didn't you try the kyb rear? is there any reason for you to stay stock completely?

[merlinq2]

No reason really. I did have a hard time finding the proper part numbers from KYB website because of the whole X thing. I say some on Ebay from a store that said they sold kyb but they were not kyb, so I figured, since I will be doing the work in Canada and I do not want to deal with the hassle of wrong parts etc, I figured I would stay oem.

The shop that lowered my car charged 350 dollars to hoist the car, drop the struts, pull the springs off, install the new springs, and re install the struts. Plus the same for the rear shocks.

Taking the car back to the above mentioned shop and they will install my new struts and shocks, re install my old springs all for $400. Don't ask me why they want another 50 bucks; frankly I don't car, they could charge me an extra hundred dollars and I would still be fine with it.

My advice; look around in your area for a suspension place, check them out and then when you are comfortable order the parts and have them install them.

The only risk you have is that the parts and labour will be covered under the infiniti warranty, where in my case, the shop will cover the labour, and I will have to fight with infiniti is there is an issue with the parts.

Do you have a reputable link for KYB?

How low? Mine doesn't seem to need them and I'm about 2" lower. Or will they tell me that I need them when I go to get an alignment?

[merlinq2]

I think mine started at 1.8" in the front and 1.1" in the rear, settled now they are more like 2.1 and 1.4 to 1.5 in the rear.
I was told that based on the new geometry, they would not be able to properly align the car, without making adjustments to the upper control arm. The camber has effaced the front tires in terms of the way they handle bumps and severely effect tire wear, lots of cupping.
Tire cupping could also be a symptom of bad struts, that is why I am planning on renovating the front suspension.
The main message is that the current hardware (upper control arms, and for that matter all of the stock bits) has been designed to work with the way the car came from the factory. Changes to the overall ride height (small tolerances excepted) will require more involved hardware changes.
In your case, with the coilover set-up, you maybe fine. I hope that is the case. In my case dropping in the springs is not ideal.
Tires are expensive, so I figure based on the mileage the car is due for new suspension anyway.

I found some for a good price considering how much tires will cost in the long run.

Really, looking at these two products, i would stay away from them. I would not install these parts on my car, the control arm looks like a cheap knock off. I would stick with a name brand or at least a reputable brand. More reserach is requied. But best of luck and let us know how you make out

[DoN_BLaZe34]

So are you saying that Eibach isn't a reputable company?? Or am I misunderstanding...


In any case, I have both the front and rear alignments kits on my M and have never had any issues. I also bought them both from Autoanything which bicsintegra has listed

[bicsintegra]

I do agree the set that is only 170 for both of them looks a little cheap even if it does say SPS components on it, I am leaning towards the eibach kit for 371, in the past my integra was on coil overs and no matter how low I went my eibach kit was always in camber after a alignment. thanks for the input.

[merlinq2]

Eibach is a good brand.
