I called Chris using the number from the business card. It seems that for 100% proper adjustment, the upper control arm has to be drilled out a little more so there is more adjust-ability with those camber bolts he makes. He said you technically don't have to drill out the c-arms, but it won't align as close to factory spec as it should.

The reason those bolts are $150 is because he makes those 1-off, he has a machine shop make those in sets of 10 or so, because there is no other manufacturer out there who makes camber bolts for our vehicles. He said Eibach makes new control arms that are perfect for dropping the car and would allow for 100% factory specs, but they are $500 for the pair.

This is the information Chris gave me, maybe someone can chime in and elaborate more if you have more info.

if your going with a small drop get the bolts but if your looking for a big drop like 1.8" - 2.25" or more get the Eibach arms.

Also for those going with coilovers it would be best to get the Eibach arms.

I understand having to drill the contol arms but where exactly do the camber bolts go?

The bolts go are what attaches the upper arms to the chassis. Using milled bolts and milling the control arms gives you about 2-3mm of play, depending how aggressive you go with the milling.

If you are unsure or want to be 100% in spec, I would consider paying extra for the adjustable upper arms.

Hi all,

I'm a new NICO member and a recent M35x owner. I've been lurking around these forums for a couple weeks now :bigthumb: . I just wanted to clarify something with the Eibach control arms kit please. I plan on doing the Eibach Pro kit springs and getting the control arms kit to put the cambers into factory alignment specs. I wanted to clarify whether or not they do indeed work (fit) with the AWD models. I thought about doing the Camber bolts like some of the other owners but there aren't any clear instructions on how to mill the factory control arms. From reading all the posts the replacement Camber bolts route doesn't quite put it into alignment spec anyway. I'm not a newbie with lowering cars, and have found a lot of these posting very helpful! Thanks :bowrofl:

Anyone heard anything for improving feel and eliminating some of the Cadi wallowing for the M56X? What exactly do you get with a "sport tuned suspension" in the Sport package? larger sway bars? revised damping rates? lower ride hieght? What is the cost to do a swap? is the money worth it or what custom options exist. I dont want/need slammed just a flatter corner and a bit tighter not break your back though. thoughts? suggestions?

^ you might want to get the rear M37 coilovers with a custom/stiffer spring rate made from BC and get the g37x fronts. I think they are the only option stateside. No one has put them on a M56 yet but im sure they didnt change mounting points between the X versions only sport/non sport and X.

Don't know if these are LP, but someone just bought some Megans.

Car Model: M35x
Struts and Springs: BC Racing BR-Type V-11 (really a combination of V-04 fronts and V-01 rears). Measurements before were 28.75" in front and 28.25" in back. Post drop measurements, right now, are 26.75" all around.
Tire/Wheel Dimensions: 19x8.5 BE by Breyton GTS-AV Hyper Silver Wheels on 245/40/19 Continental ExtremeContact DWS's
Ride Quality Stock: My struts/shocks were aging and starting to be bad so I'd say 7.
Ride Quality Dropped: 9, a little rough over significant bumps in the road (like where to pieces of pavement meet to make a ridge) but otherwise very smooth. I have mine set on 30F/30R (softest possible setting). I didn't get coilovers for performance, I got them for looks and for the comfort (since some springs can be rough).
Other Information: So far I haven't had an alignment done, so we'll see.

I enjoy driving my car again because it's not trying to kill me (going at highway speeds, if I hit a decent groove or pot hole in the road the old suspension would yank my wheel badly to either side).

It's a bit rougher than I hoped over some bumps, especially since it's set to 30/30. But, that's the price you pay for a drop.

Looks good, is the softest 30? Also did you mean 245/40/19?

Where's a good place or any place that can do the suspension work on my Infiniti M37x? Any help would be great. I'm stationed at Dover AFB, in Dover, Delaware. Will drive a bit to find a good shop. Let me know of any places. Thanks.

I purchased a 08 M35 sport last August and finally acquired Tein-H lowering springs and here’s my first post about this car! My question is do I have to worry about the struts being an issue? Also with the little drop, will camber be a problem?

Other Information: Eibach front upper and rear lower camber arms required for proper alignment. This large of a drop puts significant strain on end links, recommend upgrading to SPL or Whiteline endlinks to handle additional strain.

Do you have a part number for the endlinks? Any modifications needed to use them or are they direct bolt on?

They are direct bolt on for me with an M35. You'll want to check whether M35 and M45 share the same end link part number to see if they are direct fit for your car. I would think they probably are the same, but I know the sway bar is larger on the M45 so there is a chance they may not fit.

I got these SPL ones as they were the highest strength and best misalignment capability:
SPL front end links
SPL rear end links

Whiteline front end links
Whiteline rear end links

The whiteline ones are still a strength upgrade and are cheaper than the SPL ones.

Is this for sure that the M45 bar is different from the M35?

Maybe Im wrong, it could be that maybe the rear is different? IDK, its been probably about 9 years since I was last under an M45.
