By the way my car is within these specs and still feathers the tires

 

According to the language contained within this TSB, MY 01/10/03 Alignment should have been set at maximum 0.2 degrees, "The preferred setting is 2mm (0.08) (0.2) with no "variation" zero (0) plus or minus). Once the final adjustment is done, it is very important to not have any "toe out".

So, these "new settings" have been out since May, 2003, and I have put 6200 miles on my new tires I bought out of my own pocket. Hopefully, not too much damage has been done to the inside tread. My original cupping was starting on my OE 040s at 1600 miles, but on the outside of the tread. Now, I need to get my alignment redone. Another example of Nissan's lack of notification, instead they send engineers from Japan to tell us we are stupid and reading the info wrong.

 

Didn't I say a couple of months back that there's not a Nissan dealer in the country that can properly align a Z? Nobody ****ing listens to me and that stupid-a$$ feathering thread that I started is still going to this day.

All those provisions for the Hunters? Recockulous. No wonder my toe was 19MM!!! Go to a ****ing race shop that doesn't use a fancy-schmancy Hunter, people. It's that simple.

 

is this REALLY an update or a repeat??? this is a serious question.

 

I'm sure its just a repeat that I missed in the 78 threads we have on this site for the problem. I can only hope any damage is minimal and can be corrected. The tires are Michelin A/Ss w/UTOG of 400, so they are tough and the wear, 6200 miles, I can't see any, should even out when the toe is adjusted.

I am so frustrated with this crap.

 

New TSB, but does everybody know and fully understand why feathering occurs?

Like I keep saying all along...

1- Inner feathering = excessive toe-out, outer feathering = excessive toe-in. Doesn't take a genius to figure it out, just imagine two rotating wheels w/ toe-out. Imagine what area of the tire gets worn. That's right, the inside.

2- RWD vehicles have a tendency to toe-out in the front wheels while FWD vehicles have a tendency to toe-in. Therefore if you have zero toe, then there is a great chance you are getting toe-out under acceleration and at speed.

3- Changing toe will affect the steering characteristics of a vehicle. IIRC, toe-out will dial in oversteer while toe-in will dial in understeer. The 350 has enough understeer as-is and I bet Nissan "tuned" in some oversteer by playing w/ toe.

4- I bet the combination of negative camber and bumpsteer just amplies the "problem."

5- The 350 isn't the only car that has feathering "problems." It seems that every other 350 owner has some big conspiracy theory about it. The Acura NSX is one of the best handling sports car out there. Ever wonder why? Because it's w/ the aggressive factory alignment settings that also DESTROYS TIRES IN < 5K MILES.

In conclusion, HAH HAH. We (Droid and I) told you so.

Michael.

BTW, Droid, care to tell everybody your findings on the RX-8 we saw this past weekend?
