Hi Folks,

Here is an update to a previous posting. I had hoped to meet the Nissan engineer last Friday at Regal Auto Plaza but the Service Manager decided that they had enough to do on another 350Z without adding mine to the mix. Anyway, he said that they had updated specs for the alignment and I had it done this afternoon.

I spoke with the technician who worked with the engineer before and after the alignment and here is what he said, as best as I can remember through the senior moments.

The original specs for the alignment adjustment were in millimeters (mm) from Nissan. They have Hunter equipment and the specs had to be converted from mm to degrees. Several of the measurements were computed incorrectly. When the engineer who designed the suspension looked at the other car on Friday, he positioned the car, pick a tread block and measured from one wheel to the other and immediately said the alignment was wrong. He worked out the corrected parameters for the alignment and re-aligned the car. The service guys I talked to were very impressed with him.

Anyway, before the technician started I asked for a prinout of the before and after measurements. I scanned it in and hopefully it will show up with this post. I might have to make it even smaller but I'd like you to be able to read it.

The technician said that the major change was to set the toe to the maximum, 0.20 degrees. He was told that this had been the original spec which was converted wrong. I asked about the adjustments in the rear and he said they were minor even out of spec as they were.

The car drives even better than before and I don't feel that I have to work to keep the car from going right. I love the car and don't plan to ditch it. I've decided to get some stock in Bridgestone since I might as well get back some of the money I put out every year for tires if this doesn't work. My dealer sounds much better than the one's some of you have. Regal is also a Mercedes dealer and they are very good at customer service.

Good luck with your cars.
Not picking on you by any means DriveI65 but I take issue with some of the technician's statements. The original front toe alignment spec was stated as from 0 to 2mm with 1mm being nominal. These specifications are in the factory service manual (FSU-21) and they are given in inches as well as millimeters. So once again we are hearing the "stupid Americans can't do an alignment theory". In my case this "conversion" problem is a non-issue as all three machines that my car was aligned on used metric units of measure. It appears as though Nissan has determined that setting as much toe out as possible within this range will solve the feathering problem. Unfortunately it does not. My last alignment, and tire replacement, was done at about 9,000 miles on 9/15/03 and employed this new theory. My front toe was changed from 1mm to 1.9mm and 3,000 miles later I have feathering on both the inside and outside edges. I am deeply disturbed that Nissan is still working on a premis that has already been proved wrong so I would like to address the following to Nissan Motor Corporation on the off chance they are reading this board:

YOU CAN'T FIX THE CUPPING PROBLEM BY PLAYING WITH THE TOE FOOLS!!!

This is the first time I've thought something made sense with the alignment on our cars. Unfortunately, your diagram doesn't give the specified range for each value, ie. toe, caster, camber. Did you find out when the data would be available to our dealers?

We have had so many of our membership sell or trade their cars over this issue, it is very important we get the new alignment figues NOW, before another few hundred jump ship.

Still think we will need camber adjustment either from NNA or aftermarket.

Thanks for the scan - I'm going to enlarge a copy and place it in my LL case file. I'll show these #'s to the Tech when we meet on Jan 5th.

I don't think they've changed the range at all Boomer. All they've done is tell the dealers to set it close to or at the max of 2mm. And you can see from DriveI65's print out that this is exactly what they did. By the way, thanks for posting these DriveI65.

I completely agree. Blaming this problem on the toe being 1 or 2 mm off is ludicrous. I've been doing alignments on my own cars for a good while now, which includes a wide variety of street cars and race cars. Based on my own experience, you can run the toe within a very broad range of settings and still never cause the problems we are experiencing. But who am I to say what the problem is? For my own personal agenda, its great that they keep being stupid about this so I can just get my buyback...I've already had it with Nissan. But I do hope they'll start actually giving a crap and fix the problem. They must have engineers capable of this.


BTW, I should post this update to what I posted earlier about my dealer's screwups. I thought they had broken my tire pressure sensor. It turns out it was not broken, they're just incompetent. It took me two trips to the dealer with four different guys taking a stab at it before they could properly reset the sensors and make them all work. "Authorized dealer" my ***...authorized to screw up my car and waste my time I guess.

I second that. People WAKE UP!!!!!!!!!!!!!!!!!!!!!!!!!!!!

If the problem was as easy as sending re calibrated Shocks or adjusting the toe NNA would have done it.
A few of you have forgotten that this tread has 80+ pages and still NO FIX!!!!!
If you want to dream that a set of Konis are going to fix the problem or take thousands out of your own pockets to re design NNA's problem front suspention,that go for it!
If I wanted a project car we would not have spent $35,000 on the NEW Z.
I like many on this site are fed up with all the problems with these car's and have filed Lemon Law case against Nissan. I am currently waiting for a court date.
I am done waiting to see if a FIX is coming.{its been 12months}

More power to everyone who want's to hold out and wait another 12months for NNA to try and fix there DEFECTIVE cars.
I have chosen not to let them get away with selling me a LEMON.

Ah, well. Hope springs eternal, I hope this does partially address the problem. Anything is welcome at this time.

Does S-Tune suspension remedy the problem? And when will we find out if it works with the Track model? Every Z I have seen on the street I feel the inside of the tires, and they are all worn.

Yeah, I've gone up to Z owners and say "Hey! Check your tires... they my be cupped" At the beginning I get the look of "What are you talk'n about Willis?" - then I show proof in the rubber. One guy at K-Mart - his wife was a BBB District Mgr.


Face to face in my office last month:
I had a land developer in my office last month out of Orlando with a Touring Sunset. He had about 10,000 miles and I asked how's she holding up (knowing where I was going with the question). He loved the car except for a "strange pull to the right" and his tires were "loud". I brought this thread up on my PC and the look of horror on his face. He had been in for service 3 times and no one mentioned a thing. Two days later he called to thank me for the heads up and his car was on the rack as we spoke.

Needless to say, we didn't talk too much about his potental development. He seemed more concerned with his Z...

No problem, over the years I've had experts after me. If you'll look a little closer, I said the conversion was mm into degrees for their alignment machine and that was where they said the problem lay at my dealership. I have no idea what other dealers have done. I'm just going to have fun with my car and save a bit every month for the next set of tires unless this did fix my situation.

I'm sorry the scan is so small but posting restriction is less than 200kb however the ranges are in small numbers on either side of the readings. If you'll PM me your email I'll be happy to send a larger image.

NOW HEAR THIS!

YOU MAY BE ABLE TO IF YOU CHANGE:
1. TIRES;
2. SHOCKS/STRUTS/SPRINGS; AND
3. HAVE THE PROPER ALIGNMENT.

I don't like being called a fool and I have said for over a year, get rid of the OE tires, their tread is too soft to hold the mismatched springs/struts in their proper alignment.

Why do you or anyone else think I have changed tires?

Why am I waiting for Koni to release their struts?

Why else would the S-Tune "fix" the problem as some have said? What do you change with the S-Tune?

Springs/struts and anti-roll bars are all it is and the anti-roll bars don't count. If aligned properly, the S-Tune cures the problem, maybe? Screw the S-Tune, I want better, less expensive struts, not throwing more $ to Nissan for their NISMO line. You owe us an apology for your remarks, oz. All of us are not ignorant twits like you seem to believe, we've been through hell trying to get this problem resolved for a very long time. Find someone else to bully, you are not doing it here.

I agree many owners will never know that what is happening should not happen. I just wonder how many owners don't have the problem?

Hey Boomer, I think you might have misunderstood the last statement in that post. He was referring to Nissan the way I read it...I could be wrong though.

I do agree with you that we might be able to fix the problems as you stated. But, that should not be the responsibility of the consumer. Nissan is trying to "fix" our problem by continually claiming the toe settings are the problem, and it seems pretty obvious that the toe is not the problem.

No one is saying you are a fool.
IMO It is foolish to still believe that toe alone will solve the tire problem.
If you want to try new shocks than go for it.
The OEM Bridgestone tire seems to work fine on many other cars other than the Z. Yes I have seen the tire rack surveys on the tire. Ok so some people who bought them do not like it. I do not think there is anything WRONG with the OE Bridgestone. A soft tire alone will not cause cupping.
I have used DOT racing street tires like BFG R1s with a 50 tread wear rating on our Mustang track car with a sh.t load of toe out for cornering. The tires never cupped like the ones on my wifes Z.

Our car drives like poop with the all season pilots compared to the OE Bridgstones. It wanders all over the road. The car bounces over ruts and gets loose over expantion joints . It is not fun to drive anymore. We would not have purchased the car if it drove like it does now. I perfer the OE soft tire ,but you may not like it. Hey its your choice.

The Nismo kit may improve the tire problem but NNA has not sent me one for free or offered to install one. Why should I spend more $ on the car to correct NNA's problem?
It seems that they consider the tire wear to be normal? If thats the case then why are the giving away all those replacement tires?
My car is a Lemon and I will not be left holding on for a FIX that will never come. If you want to be the one with the 03 Z that no one wants in a few years,it is your choice. I cant afford to loose that much money on a dangerous and defective car.

OK, I may have mistaken your reference. I was only reminding people who still have the all OE setup, tires, struts and springs that all are poor choices for the car as a daily driver. The tires that were tested on the pre-production cars were Michelin Pilots, not Bridgestones, and the struts have strong compression w/o rebound control and the springs are not progressive so we get a rockhard ride on anything but a smooth surface.

Now. I am not advocating that anyone give up on ramming their car's defects up Nissan's ***, but I am going ahead with my plans because I want to keep the car, period. You must decide your course of action, not me. I am not saying changing the toe only is the fix, I think changing everything but the springs is the fix, along with camber/caster kits to adjust those values. I believe Nissan should pay for them too, but I really don't think they will because they simply do not care about customer satisfaction at all.

Disembowel them at your whim, I wouldn't lift a finger to defend Nissan, they haven't earned my respect and they certainly haven't earned my continued support of their products. Buying the S-Tune is not an option I support.

If you are speaking to me Boomer then all I can say is that I don't know what you are talking about. My remarks were directed at Nissan and their techs. And I quote...

"I would like to address the following to Nissan Motor Corporation on the off chance they are reading this board:

YOU CAN'T FIX THE CUPPING PROBLEM BY PLAYING WITH THE TOE FOOLS!!!"

I've never bullied or otherwise been disrespectful of anyone on this board. Neither have I ever stated or implied that anyone here is ignorant. I was simply stating my opinion that Nissan is wasting our time with this front toe nonsense. I've been there and done that, several times, as have many others, and it doesn't work. I'm certainly not going to apologize for that.
