Hey guys, well I have had my car lowered on the Eibach Prokit for a few months now. I had it aligned afterwards and was off slightly on both the front and rear, so I decided to go for camber kits.

This weekend I installed the front Kinetix control arm and the rear SPC camber arm and toe bolt. Went in for my alignment today and here are the results.

Front

Caster
Left 8.7
Right 10.1

Camber
Left -0.5
Right -0.4

Toe
Left 0.05
Right 0.05

Rear

Camber
Left -1.0
Right -1.0

Toe
Left 0.20
Right 0.25

Thrust Angle 0.0

One thing I noticed is that on the front right side (passenger side I presume when they give these readings), is that the ball joint casing (the red rubber thing) is touching the fender wall right above where the wheel well lining stops. Is this normal? The guy said he couldn't do anything about my caster settings unless he were to put my camber out of spec. Does this sound right?

Very confused.

 

humm, that front caster ..is that an install issue?

What value is the toe? degrees, right?...if so, that's a lot of
toe-in on the rear.

 

what do you mean is the front caster an install issue?

All values are in degrees. But isn't the rear toe factory max setting .35 for each side? if so how is that a lot of toe?

Sorry for all the questions but I am a total noob when it comes to reading and understanding alignment numbers.

 

There is definitely something wrong with the right side castor. It could be something wrong with the front right camber arm or the install. The only way your going to change caster is by moving the front control arm forward or backwards at it's connection to the frame. (the top two points of the Y) The ALLDATA spec is 7.00 deg to 8.50 deg. Not sure what the Infiniti spec is but I'll will ask the Infiniti alignment guru.

Your toe is set too severe and may cause feathering on your tires. Try these specs:

Front:
Camber: -0.25 to -0.75 deg (-0.50 deg Nominal)
Toe-in: 0.00 to 0.06 deg (0.03 deg Nominal)

Rear:
Camber: -0.75 to -1.25 deg (-1.00 Nominal)
Toe-in: 0.04 to 0.07 deg (0.05 deg Nominal)

Bottom line ..... check out the right front control arm, something is out of alignment and redo the alignment.

 

does it make a difference what size of tire they used when they punched in my car make, model etc? If you notice in these pics they have it at 215/55/R17, and they only had the settings for the 03...could they have possibly used the sedan settings?? Are they any different?

Anyway, here are the pics.

Since you're going by degrees the wheel size does not matter. It matters when
you use A-B = x mm/inches since it is the difference from lip to lip (rim to rim
for wheels with no lip, i guess.... )

The A-Arm was installed incorrectly or something is binding, etc... did you use
the correct bushing, etc that came with the kit? the caster is quite a bit off on
the right. What happens is that your car's going to squirm left when you hit a
bump on your right cause excessive positive caster will make the car toe-in.

Your right tire is going to wear faster on the inside more than your left...
since you seem to be going for wear than performance.

 

I used the correct bushing, the install looked perfect and was actually riding nicer then when I brought it to the alignment shop after.

I actually told the guy that I would like it more on the performance side so closer to the max allowable but obviously, as you can see, he did not do that. My tires look perfectly straight now which is not what I wanted, I wanted some negative camber for handling performance.

So from those pics does it look like they tried to align in within the Sedan specs? or does that even matter? I would bring it to another alignment shop but there are very few that have the G35C in their system that can accomodate getting a lowered car with a lip onto the hoist. This is all getting very frustrating and expensive grr.

 

I think they went by the coupe specs and tried to get it close to factory
as possible...which, imho there's not enough camber (as you stated) and
too much toe-in on the rear.

I would use something like this on your prokits for performance driving...atleast
as a starting point. I use more neg camber on the rear (-2.6) for my setup.

Front:
Camber -1.7
Toe-in: Total 0.08

Rear:
Camber -2.0
Toe-in: Total 0.30

 

that sounds like where I want to be at. One question, possibly a stupid one though, are the camber values you gave the total of both sides or should I be trying to get to that degree on both sides? I know I know a TOTAL noob to this lol.

 

The camber is for each side.

so...

-1.7 front right
-1.7 front left
-2.0 rear right
-2.0 rear left

 

Obviously this set-up would put me way out of the recommended range, which is fine, but will I see any uneven inner tire wear?

Also, since I will ask for these camber settings are there optimal toe settings I should be looking to get at as well?

I might as well just go in with the list of all the settings I want and just tell them to do it lol.

By the way, thanks for all the help and advice with this!

 

Yes, there will be some uneven wear on the inside treads as stock setup does too.
It's just the way it is with this suspension. Since the toe-in isn't too aggressive
you'll get decent tire wear with the added performance.

You can try less neg camber and see how it goes. I had to get my car aligned
several times to dial in my current setup and it handles pretty well for a heavy
but very comfy-ride car. Mines -1.8 front, -2.6 rear.
