I remember seeing a PDF file from the repair manual showing the coupe's alignment specs. Can someone re-post it? I did a search, but all the links are dead since the site upgrade. Thanks.

 

Front



Rear



I see you have the 350Z H-techs. Neffster also has them. When he tried to align his coupe the dealer could not get him back to spec. BUT, in talking to him and reviewing the charts and some other circumstances, I noticed several things that called the alignment into question and he plans on getting the dealer to do it again.

I recommend setting the rear toe in at 1mm per side, this will give you a little more rear camber adjustment out of the oem adjusters. I would also set the front toe in at .5mm per side. Also, do not let them take the car off the rack until they have equailized the numbers side to side on each end of the car.

 

Gsedan35, thanks for posting. Hopefully, my alignment will come out better than Neffster's.

 

They only really differ in allowable negitive camber specs. I'm setup basically to Z specs myself, it's what I wanted. If someone were to addopt Z alignment specs because it allowed them to avoid costly aftermarket alignment parts, that makes sense to me.

Here are the oem 350Z alignment specs. I tried to convert the PDF files out of the FSM into Jpeg images, but files were too large.

Camber: negative or positive
Min:+.17
Norm: -.58
Max: -1.33

Total Toe in: half number for per side
Min: 0.0mm(0.0in)
Norm:-1mm(0.04in)
Max: -2mm(0.08in)

Caster: in degree's
Min: 7.58
Norm: 8.17
Max: 8.92


rear specs are as follows

Camber: All negative numbers in degree's
Min:-1.08
Norm:-1.58
Max -2.08

Total Toe in: All negative numbers (half each number to get per side)
Min: -0.2mm(0.006in) (17 inch tire)
Min: -1.1mm(0.043in) (18 inch tire)
Norm: -1.0mm(0.039in) (17 inch tire)
Norm: -1.9mm(0.075in) (18 inch tire)
Max: -1.8mm(0.071in) (17 inch tire)
Max: -2.7mm(0.106in) (18 inch tire)

 

Gsedan35- Would you know how to convert the toe in mm to toe in degrees?
I noticed that most of my alignment places around here goes by degrees.
But then, I also noticed that the spec you posted shows inches in ( ).
The degree value I see on my measurements are the same. I am a bit
confused. Here is an example:

Spec sheet above for Front Toe-in = (0in to 0.08in)
My sheet from the shop for Front Toe-in = 0.00 to 0.08 degrees
Is this just a coincidence? (?)



Here's what I have on my car. Below are total toe
FRONT: 0.09 degrees
REAR: 0.32 degrees

What does that equal to? I think it's about:
FRONT: 2mm
REAR: 5mm

I asked the shop to got a little aggresive on the toe-in because
the springs had not settled completely (2 weeks after install).
I have about 3k miles since and my tires are wearing flat, so it
looks like my toe is about what you recommended above
(TOTAL: 1mm front, 2mm rear).

 

Same here.
I just had mine aligned after installing the Z H Techs last month.
Here are my after specs:
LF -
-1.3 camber, 8.5 caster, .05 toe
RF-
-1.2 camber, 8.2 caster, .03 toe
Total toe - .08, & .01 steer ahead
LR -
-1.9 camber, .11 toe
RR-
-1.9 camber, .10 toe
Total toe - .20 & thrust angle .01

 

Here's mine with the Z H-Techs:
front camber -1.4 (both)
front toe .05 (L) .04 (R)
rear camber -1.6 (both)
rear toe .10 (L) .09 (R)

 

Cool, looks like we're all on the same page.

I'm not sure why the j-specs are so damn aggresive. I've been talking to 350GT
owners in Japan and they're complaining about premature tire wear on the inside
treads...their settings are using too much toe-in front and rear. (2mm front, 5.4mm
rear). they say this is the only way to completely eliminate the slight wandering
effect resulting from lowering... but that's quite a bit of compromise on the tire
life. (typical 10,000km and their tires are half gone).

 

same data sheet for the sedan?
